My car idles fine at a cold start but after Im driving and a depress the clutch, the car will idle at about 1300 rpm and then go down after 2 or 3 seconds then it will idle normally. It almost always does this after Im driving and then I go to depress the clutch. It used to go right down to about 800 rpm as soon as I put the clutch in. Does anyone have an idea as to what may contribute to this lag? Thanks in advance!

 

modded?
tuned?

could be an issue with your idle. try the idle reset procedure.

 

Is the clutch vacuum assisted? Sounds like a vacuum leak to me. Also try the advice above.

 

How do you do an idle reset?

 

how do u reset the idle? No, there arent any major mods and it never happened before I put it into storage. I appreciate any advice.

 

pull the battery cable for a while....will clear the computer of all the "learned" values.

could also try just unplugging the TPS with the ignition on...let it sit for a minute then plug it back in.

then start it up and let it idle for a few minutes

 

alright, ill give it a try. Thanks!

 

yup sounds like a vacum leak somewhere. Or maybe a sensor. Is it throwing a code?
