HOW BAD IS MY ENGINE BROKE...

bought my 92 si to help save milage on my 98 accord. after driving for a week i enjoyed and prefered it over the accord for most of my commuting. it does leak n probably burns a little oil b/c i have to add about a quarter quart of oil every month. i've had it for a year now with good reliablity n last nite driving home i noticed the oil and battery light go on at the same time... (****).. i pull over quickly n turn the engine off. i checked the oil levels n its fine. i tried to start it n it stalled.. (****).. i tried to start it again n starts but runs rough n want to stall but no warning lights r on...
any feedback on wat problems i got to deal with???

Re: HOW BAD IS MY ENGINE BROKE...

not knowing what "running rough" means, i would have to advise you to start with the basics. if you can, take a picture of what your spark plugs look like out of the engine. don't clean them up. spark plugs can say alot...

to clarify, define rough... does the whole car shake? do you know what a miss feels like? will it carry its own weight right now?

i could make guesses as to what your problem is, but right now thats all they would be

Re: HOW BAD IS MY ENGINE BROKE...

the car is idling really low n wants to stall n yes it shakes on idle. the car can carry its weight after 3k wen i drove it home. i hope its not a blown motor. drivin in the accord is just not fun n will make my commute just that longer :(

Re: HOW BAD IS MY ENGINE BROKE...

the rain finally took a break. here is a pic of my spark plugs. i installed them about a year ago. started the car again n engine sputters 800-1.4k on idle which it never did n the car shakes abit. do u think a failed oil pump? odm reads about 182k.

Re: HOW BAD IS MY ENGINE BROKE...

with the plugs in and the wires attached, start the car and using an insulated pair of pliers carefully pull off one wire from the distributor. if the car runs the same, you found a bad wire/plug. if the car bogs down more then that wire/plug was fine. either way shut down the car and reattach the wire then repeat the process for the other three wires.

Re: HOW BAD IS MY ENGINE BROKE...

did the test disconnected each wire one by one for a few sec n only one wire made the engine bog down. i assume i have 3 bad wires.?. i checked continuaty on them n test with no open. can the engine start wit only one plug firing..? i did noticed some corroded contacts on the distribution cap and a little worn out rotor.. parts store r closed now :( will replace them. really apprieciate the inputs.

Re: HOW BAD IS MY ENGINE BROKE...

Try replacing your cap, rotor, wires, and plugs
Your plugs are covered with carbon burnt oil and rich fuel mixture are your usual culprits.
Your car wont run with only one cylinder firing but weak spark will cause rough idle. Therefore split insulation on your wires and bad contacts on your distributor will cause weak spark.
When you perform a cylinder power ratio test (I.E. removing spark from a cylinder) each cylinder should drop evenly @1000 RPM each cylinder will drop your idle by 250 RPM. If not and one respective cylinder causes a major RPM drop your spark on one or more cylinders is to blame.

Re: HOW BAD IS MY ENGINE BROKE...

will have those items replaced 2morro. its just weird that my lude ran good n pulled fairly strong (love the h23) since i had it for about a year n then all of a sudden those 2 lights lit up.. after that engine not runnin right.. i do good on the oil level which i check twice a week, change oil on time. i use chevron, 76, if not around then arcco gas all at 91 octane. i kno the engine seen better days but ever since i had it i kno my lude feels loved again.. i do hav plans to do a swap (h23 or h22; havnt decided yet) in the future, but not ready yet. hope i hav more time b4 it dies

its not necessarily the wires but something in the electrical path from the distributor to the plugs. so just like others said you should do a basic tune up replacing the plugs, rotor, wires and cap (in order of price/likely hood to fail in case you are limited on funds to do it all at once)

Re: HOW BAD IS MY ENGINE BROKE...

Okay not to break any ideas but , the problem you gave was bat,and oil light on that usually means charging system ,like alternator ,and battery ,beside other issues you mention ,need more information to go for better trouble shooting .

Re: HOW BAD IS MY ENGINE BROKE...

ok did the replacement of cap, rotor, plugs, and wires. definatly helped on the sputtering problem and now is fairly idles at 1k. there are still some issues that is not normal: the car still shakes a little (reving up is not as smooth also); the exhaust louder than usual, and i do smell fumes out of the exhuast. i believe its gas. how would the car run richer without any adjustments? my voltage with the car on is 14.55v at the bat post.
ps cavscout, my bad foreign accent is just bad grammer. english wasnt my favorite subject. sry :D

Re: HOW BAD IS MY ENGINE BROKE...

if you smell gas coming out of the exhaust, then generally speaking, you have a cylinder missing.

but, like i said in my first post, the basics. if you have tested the spark plugs, and they all work, then the next step would be compression. have you tried a compression test? if i recall your magic number should be in the 160-180psi range... memory is kinda hazy on that one though, i would look it up if i were you :)

Note: if you do find a cylinder with bad compression, try dropping a bit of ATF in that one cylinder. old mechanics trick for when you blow out compression due to flooding the engine with gas.


i doubt the problem has anything to do with the charging system, but if you feel it might, autozone will test both battery and alternator for free.

Re: HOW BAD IS MY ENGINE BROKE...

I'm wondering if a fuel injector/resistor box crapped out and is flooding one cylinder. That might have caused detonation (instead of ignition) in the cylinders which could have burnt up your plugs/wires in the first place. Replacing them would then help (as your current situation). How did the compression test go? what motor are you running (include if it is usdm or jdm)?

Re: HOW BAD IS MY ENGINE BROKE...

wont get the test tools till later 2nite after 10pst. the motor is usdm h23a1. i'll look in the manual to c if i can find on how to test the resistor box. i asume its the little box on the right corner with heat fins..?

Re: HOW BAD IS MY ENGINE BROKE...

I just wanted the motor info to check if you had the low impedance injectors with the resistor box but it looks like you already figured that out. let us know how the injectors look. good work so far

Re: HOW BAD IS MY ENGINE BROKE...

sry 4 delay. dont hav results for compression b/c the parts zone i rented it from had mixed matched parts that didn't fit together. will buy one later 2day after wrk. my bro had brought the rest of tools and some. i wish i did the testing, but my bro looked a little tired so i let him b.. i was in charge of turning the car off and on.. (that was fun:( ). his results was: fuel pressure 37psi, could not get proper timing b/c could not get proper base time, all plugs had spark and looked normal except plug #2 had an abnormal rhythm, main sensors r fine except for o2 sensor(his scope reads that it opens half way and doesnt switch wen fuel increases). he does suspect there is something wrong with cylinder 2. he gave no explanation on what the issue could b. i think he was too tired to think. I wish he had more time but hes busy workn n installing a turbo kit in his 240sx and getting it tuned for a drift meat in june.
dont kno if i worded some of the results properly. hope it make sense.

Re: HOW BAD IS MY ENGINE BROKE...

well like the title of this thread HOW BAD IS MY ENGINE BROKE...? got the compression results and they look real bad: 1@ 150psi; 2@ 0psi ; 3@126psi; 4@ 120psi. looks like im garagin the lude for a while.. i only got a few more ?s left...
1. can using regular oil ever since i got the car and using high mile oil a week n a half a go cause this?
2. can i ask if this engine is worth rebuilding?
3. how much more work is to swap between h22a1 odb1; n h22a4 odb2?
4. is the 10hp worth the extra work?
5. if i go the easier way can i make a jdm h23a work with my current setup?

Re: HOW BAD IS MY ENGINE BROKE...

1. no
2. yes, use OEM parts though, don't cheap out on ebay
3. how much do you like electrical bs?
4. yes
5. yes, it is direct plug and play. i think they have different regualtions on emissions though...



did you try putting a little bit of tranny fluid in cyl #2? like 10 drops worth. it won't hurt anything as long as you don't flood the engine with it. i have fixed what would have been an $8000 rebuild on a jag by doing this, among other cars.

edit: a friend is telling me i could be wrong on #5... google should help alot though.

Re: HOW BAD IS MY ENGINE BROKE...

i think the atf trick worked. wen i did the compression tests all plugs were fouled up except for plug #2 which was still clean. after i dropped some atf, i ran the engine 4 a while then reved up a little 4 a few minutes. the car still runs rough on idel, but stable at 1k as b4. but exhaust does not smell rich anymore. turn engine off n pulled plug #2 just to check. now that plug looks like the others. won't kno 4 sure it worked till i run another compression test 2morro. it looks like there might be some light for this engine.
the main problem now looks like im gettn a lean input signal somewhere cause all plugs r fouled up with black carbon.
thanx for that miracle tip audiophile n givin me more hope

Re: HOW BAD IS MY ENGINE BROKE...

oh n thanx for answering my other questions audiophile.
my main goals for my lude would be havin vtech n 200hp under the hood. might go turbo later. im not afraid of electrical wrk as long i hav a refrence point. if im forced to do the jdm h23 can i swap the emmission parts from the old engine?

Re: HOW BAD IS MY ENGINE BROKE...

just go home. waitn on compression tool. for ish n giggles i went around the block to c if it would hold or attempt to stall out. after the atf fix the engine feels more stable and was able to hav a run around without the feel of stallin while in gear(still idles rough). b4 the atf fix it would definatly want to stall in gear if i dont keep the rpm higher than 3k.. still no warning codes. after parking i just decided to check for codes 4 the hell of it.. what do u kno i get a 43 code. under PZ's DIY link it indicates fuel supply (thanx PZ). i will check fuel pressure again. with another guage that hasn't been rented out n abused. looked in the manual n loox like it can also b o2 sensor related. my bro's scope did show it was not 100%. he did also mentioned with odb 1, o2 sensor doesnt trigger warning code unless the ecm reads an open.. is that true?
anyone hav code 43 without the MIL on while driving?
is there any way to test o2 without ecm test harness?
