idle will bounce while @ a red light

[92whiteboicb7]

i have the 92 ex w/cold air. exhaust. nuttin major...the alternator is fairly new cause thats what i thought it was. but it still does it...when im at a red light it will bounce from the normal spot down and then go back up and keep doing it till i go again it never really bounces so low the idle dies. but it gets really close. wondering if anyone has any input on it.

and btw the car is 5speed and ive checked for vaccumm leaks.

it can be many thimgs like your idle control or like your vaccum whoses... it happens to mine we am at a light or heats up....

Its most likely your IACV (Idle Air Control Valve). Lots of people have this problem, try a search to find their threads.

[92whiteboicb7]

i tried doin the search before i even posted...alot of ppl this only happens to them when its cold or when its hot. mine does it all the time. but ill give the iacv a try. anything is worth a shot. lol thanks

[92whiteboicb7]

wow im an idiot. i already cleaned that out. my boy told me to check that a long time ago and it was fullll of black stuff. lol but it still did it right after that.

air in your coolant? really small vac leak around TB?

[92whiteboicb7]

well my boy just showed me this link on the site for everyone that is having this problem. and i think it covers it all. so gotta try the fitv tomorrow deff. so if anyone is having this problem i would refer to this link and btw thanx torqstr for this!

Here's the Link!

well, i've been having the same issue.

FITV--remove plate. clean it out, tighten down white cover if it's loose & all the way up.
IACV--pull and clean. if nothing comes of that, check to make sure you're getting ample coolant flow to it. If that still yields no results; replace.
TPS--no one mentioned this yet, did they? calibrate it. if you need instructions, search around here or check your Haynes. Not sure if chilton explains it or not...

Check once more for any vac leaks. Throttle cable/TB plate??? process of elimination my friend

Spray Carb Cleaner around the intake manifold to find out if u have a vacuum leak in the hoses or gaskets. I just found my leak that way after check the normal parts on the intake. Intake gasket in my case.... Good Luck!!!!
