This truck has had a lot of recent issues that were caused ethanmol phase seperation
read more ethanol seperation here: by Phase Separation in Ethanol Blended Gasoline
During that adventure, the following was replaced. (ALL OEM)
It runs fine with everything except idle. In gear, it will rock the truck hard, and lights will dim with every surge.
It surges ~100rpm. It is idling at about 700rpm.
The (stock) exhaust sounds like a hemi.
IAC checks out fine (I think).
Methinks that there is something very wrong with the mixture. Any ideas are much appreciated.
