hi .. I got problem with me idle ..it never stay a the same place .. it always play around 700 and 900 rpm ...

and something when I roll and I push the clutch the rpm go at 2500 rpm .. so I stop the car than restart the engine and everything become normal ..???

what do you think I can do

thanks

check your tps voltage, using the green wire to test with, ground the other lead to the body, make sure the range is at .980 with the key in the on position. also check and see if you have a vacuum leak. either one could do it. I would do the both

What kind of mods do you have? Clean you MAF lately? IAC?

24# injectors are a tad big for a stock motor

i just changed my IAC and it made mine stop doing that a little bit, it still fluxuates but not as bad as it did
