Need some help guys. I have recently replaced my idle air control valve, throttle position sensor and thoroughly cleaned the TB with TB cleaner. Here is the problem. When I start it up, it starts normal but after about a second or 2, it seems like someone is pushing on the gas pedal pretty good. Very high idle for about a minute and a half then back to normal of about 750 RPM's. Did I do something wrong and / or is this a simple problem to fix ? The TPS is not adjustable or at least you can bot move it either way.

Thanks for your response. I want to fix this screamer this weekend.

 

Did you reset the computer by disconnecting the battery?

Actually, this is one of the 1st times that I did not reset the battery. I'll do it and let you know.

Thanks

 

is it cold out? that may just be the computer warming the engine up. mine does it slightly when its warm out side but when its down under 50 or so it really humps it for a minute or two until it reaches a temperature the computer likes.

 

Resetting the computer looks like it did the trick. Glad you all check this thing out on the weekends pretty often.

Thanks again for your help you two.
