Hello! Welcome to justanswer!

 

If you cover the throttle, does it still idle high?

Customer: replied 5 years ago.
how do you cover the throttle
Expert:  Anthony replied 5 years ago.
With your palm, cover up the throttle body inlet. Does it idle down then or does it still idle high?
Customer: replied 5 years ago.
is this with the air cleaner disconnected bypassing the maf sensor
Expert:  Anthony replied 5 years ago.
It will make the check engine light go on but do the test anyway to see if the idle goes down or not.
Customer: replied 5 years ago.
the engine light is on now, when you step on throttle the idle goes up than has a delay before coming back down to idle
Expert:  Anthony replied 5 years ago.
Right but if you cover the throttle, does the idle go down or not or does it stall?
Customer: replied 5 years ago.
stall
Expert:  Anthony replied 5 years ago.
How high does it idle?
Customer: replied 5 years ago.
don't know exactly it idles down the road at 30mph
Expert:  Anthony replied 5 years ago.
Thats bad computer or the wiring from the idle air valve is shorted. Check the wiring and if its ok, replace the engine computer. The only other thing is a big intake leak which was proved by covering the throttle.
