usually this means the IAC motor (loacted on the underside of the TB) has gone out. has your truck had a bad idle. quit while idleing?....quit when you turn the AC on? if not reset the ECM and see if it reappears

Not really a topic for the Lounge. A perfect candidate for the "How To Mod and Repair" section though...

actually it has stalled out on me for no reason. I will reset the computer like yoiu said to do.

spooldup, did that fix the problem? I have the same error, even after I replaced the IAC. Thanks!

Often IAC problems are due to clogged up IAC passages. If it has higher miles (100K+), take out TB and clean out the passages under the bottom plate of the TB, you will need new gaskets as well.

I have cleaned my IAC and the entire throttle body several times. It would work better for awhile, but issues would return eventually. I finally replaced the IAC and never thought about it again.

well this would be the second new IAC, hopefully after I clean the TB everything is good. I have a TB gasket kit on hold so maybe I can do it tonight. I sprayed TB cleaner into the throttle body and that is when I started having problems with the IAC. Thanks for the help guys!
