I have a bit of a problem and would like to see if you can help me troubleshoot.
I give the truck a little gas (maybe 15-20% throttle, not getting into boost but close to zero vacuum) i let off the gas but the motor keeps acceleraring. I had to throw it into neutral, one time the revs came down, another time i had to shut the truck off then turn it back on because the revs kept up going up. By the way, when the revs do come down there is a lean pop out the exhaust.
Has anyone ever heard of something luke this? Is that something that could be fixed with tuning or is it something wrong with the computer or throttle body? There are no codes
