Thread: E85 very rough idle.

Here is the link. I see you are already on the hptuner forum. Good luck getting much help there, lol. If you don't have a small block you won't get much attention. But this guide is the simplest and quickest I've found and is very easy to follow. If you have any questions just hit me up.

HPT forums suck!!!! Zero help there and outdated information. Once in a while 5FDP pops in and helps.
