Re: How do I kill this automatic function?
Benny,
Have you found the problem? I can say that without data logging you may never find it.
Here are a few things that will cause high idle. without reading the computer you will have to guess.
plastic shift indicator at the base of the steering column is broke or cracked and the truck thinks it is in gear when it is not
02 sensor to far from the manifold and not going into closed loop ,needs heated 02
temperature sender for the computer is off and reading cold.
possible vacuum leak.
TPS set wrong.
here are some screen shots of the program. you will find your problem in one minute. If you want to PM me i can walk you through it.
My TBI idled high and i wasted a lot of time and money guessing. My issue was the shift indicator and 02 sensor.
sticking IAC.
calling for AC by default.
