Misfire, sputter, bog, poor divability, help!!!

So I have had my 95 lude for about a year now, it's got the jdm h22a engine with appx 60k miles. Ok to begin when I start the car it runs ok, but has a very sparatic idle sometimes, not all the time. The warmer it is, the better. So when I start driving, for about the first 1/2 to 1 mile, it sputters, and bogs, and has major power loss. It does it bad enough that my car will jerk and pull and it's really bbeen pissing me off. Its like it gets its power for a second and then loses it again, then gets it back, then loses it again. This happened about a week after I added sea foam to the fuel tank, and not very much either. Since then I have replaced all spark plugs with ngk iridiums, ngk spark plug wires, msd distributor cap and rotor, New tps sensor, I have made an egg block plate, cleaned the iacv, ran sea foam through the brake booster line, New fuel filter. I checked for loose grounds and just can't seem to overcome this problem. I want to check the vaccum lines but can't seem to find a diagram that I can read well. All in all, I have tried so many things and nothing g seems to work. Also, if I floor the car, it will sputter for a bout 10-15 seconds and then bam, it's off like a bat out of Hell. Possible that a bad fuel pump would cause this? Someone please help as this is my dd and cant have it out of commission much longer. Any suggestions will be tried if I already haven't tried it.

Also, when I unplugged the iacv when idling, and plug it back in, it makes a sound similar to a backfire, or it is a backfire. And would this be the result of a plugged or faulty injector?

Thank you Eddie for replying. The Fitv is deleted and so is egr. I don't have a check engine light, and by tstat you mean thermostat?

A loose ground wire will make it cut out like that?

Re: Misfire, sputter, bog, poor divability, help!!!

I checked the ground on thermostat housing, and from the battery to the frame. Took them off, polished them up, put them back on, nothing still the same. I also watched the fpr when revving it, and it went up. while it bogged, it didn't move. It's at 60psi. I do have a small coolant leak, but even topped off and bled, it doesn't help any. Idk what's going on with this Thing but I hate it so much.

Re: Misfire, sputter, bog, poor divability, help!!!

I believe so auzbb. Like I said New iridium plugs, ngk wires, msd distributor, New ignition coil. Fairly new vtec gasket and cam plug seal, and valve cover gasket. I did a vaccum leak test with brake parts cleaner, and it showed a leak where the throttle body meets the intake manifold. It's a small one so would that cause this big of an issue?

Re: Misfire, sputter, bog, poor divability, help!!!

You'll be surprised how much a small vacuum leak could cause surge idling. A bad ground can cause idle issues(power loss), the ground where the thermostat is at is for the Ecu. So yeah, it's pretty important and will cause idle problems,

Re: Misfire, sputter, bog, poor divability, help!!!

I had the same problem, when it was turned on it would idle fine, once I started driving it started to boggle, jerking. I looked at everything, no cel light, but it ended up being a bad ground. The looses ground will cause the ecu to cut it and out. I was convinced that it was the dizzy or something with the ignition, I sure was wrong

Re: Misfire, sputter, bog, poor divability, help!!!

Are there any other "important" grounds I need to look for? I will probably unhook every one I find and clean it up. I just took my distributor off, and the cap had oil in it. Bad seal?

Re: Misfire, sputter, bog, poor divability, help!!!

Ok so problem fixed I guess. After cleaning the **** out of the distributor internals, and I foind oil in the wiring harness for all the plugs below the distributor. Unplugged them all, cleaned them inside and out with brake parts cleaner, slapped everything back together, and no more stutter! Ran like a raped ape, now that I think about it, this car is way faster than I ever thought it was. So rule of thumb, make Damn sure the gasket and o ring on the distributor and cap are good or you'll end up with oil on the cap. And I unfortunately dumped about $2000 into this car on new parts when all I had to do was clean the cap out. But I'm a little mad about how it got oil in, as the cap, gasket, and o ring were all brand new 3 months ago. The gasket was broke and I don't have another, so I used gasket maker along with the old gasket. So far so good.

Re: Misfire, sputter, bog, poor divability, help!!!

Oil won't get into the dizzy through the cap seal. If you unbolt the whole thing and slide it out from the motor there is a little o-ring on the end where the dizzy attaches to the camshaft, this is where the oil gets in. Might be worthwhile replacing this too or it will just fill up with oil again.

I did replace the o ring, the set I got came with 6. Should be good now. I ran her good last night with no problems

Re: Misfire, sputter, bog, poor divability, help!!!

I replaced it about 3-4 months ago to, that's where I was confused. Do these o rings go out a lot? I have a timing light, so really not worried about but still.

Re: Misfire, sputter, bog, poor divability, help!!!

Oops, I must have skipped over the bit where you said you replaced it already. I just changed the o-ring out for the first time (I'm assuming) on a 22 year old car with 130k miles on it and it hadn't started to leak quite yet, there was a little dribble of oil under the distributor but the inside was clean so this could have just been from the gushing cam seal next to it. They do go hard and crack but not in the timeframes you are talking about. Did you go genuine? Did you coat it in oil when you put the new o-ring on (apparently this is important). There is an supposedly an internal seal too but I can't find any parts listing for it, and there is nothing in the service manual on how to get this thing out so I guess if this goes then Honda expect you to replace the whole unit. You have to be very careful when putting the dizzy back in too, I know on mine it took a bit of aligning to get it perfectly seated on the mount.

I don't believe the coupling or bearings in our distributors are serviceable either, if these are rooted it can cause oil to get in. If you pull the distributor (again) and give the shaft a wiggle this will tell you if this is ok, if not then you're up for a new distributor too.

In the meantime, just keep an eye on it. If you start getting oil in it again then dig deeper, otherwise it might be good now.

Re: Misfire, sputter, bog, poor divability, help!!!

Well the last two nights I have had to clean oil out of the cap so something isn't right. The part that plugs in to the head from the distributor is very wiggly, so I guess I need a new distributor. I'm just happy I found the problem that has been haunting me. Like I said, I have done little to no mechanic work until I have gotten this car, so it was my learner, and now I know it ok, but not great. So that said, I will get a new distributor as I haven't done this yet. Seems like no matter what oil leaks into the cap, and drips from the bottom down onto my block and tranny so yay! I get to spend more money lol. I appreciate that but if info, because I noticed that input was wiggly but couldn't find anything online about it so that helps a lot. And I did put oil on the o ring. I guess I will get the dizzy and post back if this solved my problem. I also have to get a temp sensor because I was removing the old one to get to my coolant hose behind it and I broke that mother ******! Oh well.
