My car, sometimes doesn't want to stay idling or idles rougher then usual. After it warms up it tends to go away....sometimes. Other times, It runs bad, it wants to stall (almost) every time I push i the clutch and it idles really rough.
Any idea what could be causing this?

 

Sounds like the TPS need adjustment. Now having said that it doesn't tend to drift so have you touched any thing or is this a new problem. Rough idle can also be an indication that you need to do a tune up (plugs, air filter).

Confirm: when you push in the clutch the idle changes?

 

It’s hard to pin point a problem like this quickly. It could be one problem or a combination of problems. I would venture to say it is a vacuum leak. You can test this (I like this method because it is less dirty) by spraying some Windex around the motor while it is idling and when you hear the change in idle you will have found the general area (you can also use carb cleaner). But aside from that when is the last time you gave the car a full physical? I would check the condition of your spark plugs and wires. Make sure the TPS is adjusted properly. Then you got fuel filter, air filter, O2 sensor, the list goes on. You can never beat preventative maintaince.

If the car is moving its fine, as soon as you push the clutch to stop it stalls(doesn't happen every time, just most of time, lately)

I just changed my spark plugs a few days ago, my fuel filter, air filter, coolant, etc. have all been recently changed.


I'll have to check on the vaccum leak, thought it might be that, but figured I'd see what else it could be.

 

Its a new problem.

 

whenever you have a rough idle, always check your compression first before spending money on parts

 

and always test parts before replacing them. spending $300 on a TPS assuming it was the problem may just be 3 bills down the drain.

 

Well, my car stopped the whole wanting to stall. I can defently hear the vaccum leak. I tested my TPS seems to be bad...
