irritating idle please help!

ok so here's my problem i'll explain the best I can. I've got a 5spd 94 jdm h22a in a 92 si. on a cold start I have no problem, warms up just fine. As soon as I reach operating temp my idle will begin to jump between 500 and 1500 with lights on and 700- 1200 lights off. this seems to only happen once the car its coming to a stop or completely stopped, very irritating at stop lights. also if I start the car and let it warm up without driving it it will have a bouncy idle as soon as the radiator fan kicks on. I also have started getting a cel when I accelerate in one gear, any gear, mainly fifth (because passing people on the highway )for about 5 secs or more, if I turn the car off it goes away until I do it again. jumped the obd1 plug it blinks constantly non stop like this blink....blink....blink.... any advice would be great on either problem.

What I've checked:
iacv(cleaned), fitv(cleaned, removed and screwed the plastic thing back in), did coolant bypass of fitv and iacv, checked all vacuum hoses and sprayed gaskets areas with carb cleaner, cleaned egr(not ports), seafoamed fuel tank, crank case, and intake (runs better now (: ), complete coolant drain and refill(by the book), had plugs changed about 5 months ago ngk iridiums(old ones were black with soot off some sort), I've ordered new plug wires, cleaned the dizzy cap points, the coil wire end not connected to the dizzywas covered in blue stuff (also like soot) the connector there looks burnt(cleaned that out)

both problems have been occurring for about 1 1/2-2 months could it be a bad connection with spark plugs or fouled plugs? any info would be awesome.

thanks in advance.

Check that CEL, blinks are codes. No matter how many times, it can fast blink up to 9 times, pause, and keep going, its like morse code.

Carefully look at the blinks, quick blinks are 1, long blinks are 10. And it'll pause itself and do it again. Google it, you'll find a guide.

CEL is godlike for a rough idle, I wish I had one to fix mine. =/

Re: irritating idle please help!

ok so just checked code 1 and 10 I think it might be a possible 10 -engine temperature I've noticed if it is raining out my hood will evaporate any water on it as soon as it touches it after ive been driving for a while, but my temp gauge says its right where it needs to be no over heating problems. maybe the excess accelleration would cause the heating up?

Re: irritating idle please help!

Is it 10, 1, or 11? Haha. A short blink then a long blink stands for 11, a single short blink will be 1, a single long blink will be 10.

It takes a second to watch the pattern and catch the code.

As for your question in my other thread, the thermostat is an easy change. If you have 20 bucks you wanna spend just pick up a new one, or if you're tight on cash take your old one out, put it in boiling water, it should open at 170-180 degree's.

The theromstat is a round spring looking thing. It's a little messy to get to, coolant will leak all over the place. Drain your coolant till the level is below that top upper hose coming off of the rad. Its not much. Even then, do it on grass. The theromstat is located right there the bleeder is, gotta remove the intake to properly get to it. There's the sensor plug, I unplugged the EGR to get it out of the way, and it's 2 bolts. One's visible, one you need to sneak an extended racket to get. Simple once you see it. When in doubt a google search will help you, thats what I did for a picture.

The thermostat is sitting right there, pry it out and do whatcha gotta do. Pay attention to the seal, and which way its facing. I rushed, didnt take attention, and took me a bit to figure out which way it sits in.

Re: irritating idle please help!

is it possible to over load ther battery and get an idle problem like when my fan kicks on or I turn my lights on. the guy before me had a sub attached to the positive of the battery but upon taking the sub out he left the attached positive wire and I assume the ground wire also I also noticed looking at the thick negative terminal wire that it is bare(no rubber sleeve) at the end where it connects to the bottom of the engine idk what too. but it looks to be fraying sort of could that cause a bad ground and an idle problem

Re: irritating idle please help!

Alright so ive changed the thermostat bled the coolant afterwards ive noticed it s happening less often now but when it doesn't happen and I'm idling at a light or something my idle is very high like 1500 I got new spark plug wires but but had to send them back because I had ordered a set unknowingly that had no coil wire I thought they all camewith a coil wire oh well. But upon looking at my wires I noticed a tear in they coil wire right where it plugs into the coil. My car was on at the time and I was looking at them reached down to move some stuff and got a nasty little shock When I touched the coil wire that's when I noticed the tear in my coil wire haha. So hopefully when my new plug wires come in my idle problem will be solved. If any one thinks this might be my idle problem speak up.
