its that common prob when you push the clutch in while driving the idle will drop all the way down then back up to stock.. my car does it. it has shut off like 3 times now but only at like LOW speeds. i heard that its just one of those things you cant really fix. i have never tried. anyone ever get it worked on to where it just drops down the stock idle.


i am at like 5000 RPM just cruising. and i push the clutch in. the rpms drop all the way down to about 100, then goes back up to 900 (my idle)

thanx

 

Try closing the throttle plate a little and opening up the idle screw a little more.

 

throttle plate as in butterfly right.


well, maybe i should first clean out the TB. my gas pedal gets stuck sometimes. i am thinking that has to do with it.

 

If your throttle sticks open up your throttle plate a little more. That might be doing it to.

Yes throttle plate / butterfly

 

kewl.. well i just found out that my TB doesnt have that screw that adjusts the plate. i got one now and im gonna put the screw in and see if things will improve.

thanx

 

well, i put that little screw in. i opened it up. still didnt work. i even had it opened it up to where i was idling at 2K RPM and it still dropped down to about 200 RPM then went back up. ima clean the TB tomorrow.

 

i have the same exact problem...but only when i have my headlights on....what car do you have?

 

its my integra.. i have Jun3's in there. i think that is the prob.

 

repalce / or clean the IAC VALVE, this will fix your problem

 

IAC is the one behind the intake manifold right...? yeah i've tried to replace it/clean it.....still does the same

 

What minimum voltage reading do you get from the tps sensor? Compare that to specs in a manual (OEM) If its lower than factory specs, .45v ( I think? , someones borrowing my manual) that could cause a fuel cut and drop the idle.

 

i "fixed" my problem with replacing the ecu...try it and see if it helps....now im running non vtec not fun at all!!!!
