what can cause that much idle bouncing and no rev'ing of the motor?

running super rich

 

3k to 10k?
Are you sure you don't mean 300 rpm to 1,000 rpm?

i wish i did, but thats what it is 3k-10k. the worst part is sometimes it will hit below idel rpm and feel like it's missfiring (lack of power, then kick back in out of no where)

pls

 

Have you tried checking your IACV? See here: http://www.g2ic.com/forums/showthrea...ht=idle+bounce

Also, do you have any mods that might have caused this?

 

i've actually done the cleanning for the IVAC and replaced the EVAC. What i said before about 10k, i ment 8k, but if my tach went to 10k i'm sure it would bounce to that.
I took off the vacuum line to the FPR and i could not feel any pressure well not enough to suck on to my finger. I put on my B&M fuel pressure guage that i've had for ever and it's running about 35psi w/ the FPR vacuum line on.

I've notice another thing the idle twitchs too. like little jumps here and there, ussally around 3k it will either jump + to around 7.5k or bog down to below idle rpms then KICK back in. I try to catch it by puting the clutch in.

Another thing i've noticed is that my fan is running constantly...i don't think it's supposed to do that..

Oh NO MODS at all just a stock 4dr 1990

 

Dang, that's wierd. As for your fan, maybe your fan switch or temp sensor is trippin. As for your idle problem, well, I don't know what to tell ya. Well, I do have a suggestion though...try posting this over at G2IC.com. There's a ton of guys over there that could probably help you diagnose and solve this problem.

 

when I had problems with my ecu program, the car would not rev past 3000rpm and ran and stumbled exactly how you explain it.

try resetting your ecu or swapping it for another.

 

did the reset, i'll be trying another ecu hopefully tonight.

 

Check the FITV

 

I'm having the same problem with my 90 Teg how do i do IACV cleaning?? I've also been told to send the Injector to RC Eng. for cleaning.

 

uhhh 3000 to 10,000 rpm, after doing that only a few times I think your engine would have said buh-bye already.

 

it's on the back of the intake manifold, take it off and clean it w/ carb cleaner spary it let it sit and then blow it out w/ air (or air dry). It's easy to take off only two bolts holding it on and coolant lines.
The EVAC just take off the TB, and it's right below w/ two coolant lines going in. IVAC FITV same thing...

PatrickGSR94 , yea i know that but the motor is not reving w/ the tach bouncing, just dying when it goes to 0 on the tach. I wish it was reving then i'd know it was the ignitor or something simple...but no this is a pain in the ***

 

check your spark plugs

 

you also said that you fan is running constantly. when did you change your thermostat last ? i have a friend that's a honda tech at a local honda garage, and that seems to be a common problem he said with honda's is the thermostat. it's a cheap fix, might wanna try that.

 

brand new NGK spark plugs put in when i did the swap
thermostat brand new too...i have another one thats in the package, i'll try that one tommorow see if it does anything.

 

well i was tinkering around again going over what i have already done, oh yea good ecu tried it on a crx, and i started to finger my throttle and low and behold the DAMN DAMN DAMN YOU TO HELL YOU DIE NOW IVAC is the problem. I covered it and the motor died, doesn't it just **** you off when you spend hours on something that you've already done
