Partial throttle stutter
Has anyone else experienced a part throttle stutter around 1800 rpm? Ours has been at the dealership for 2 days trying to figure out why we have this misfire and why the ECM isn't detecting it. Of course, if we just keep the revs over 3 grand the thing runs like a beast and the MRT V2s sound awesome...

Just got mine fixed.. its the torque converter. Do a search and you will find a couple threads. It has been an issue on multiple cars.

And since is in (in effect) a design flaw (though it performs within specs), GM will never admit they screwed up. The VMax throttle bodies are great, but it will be on your dime - well worth it.

Is this for the cold-engine bucking that happens at part throttle, or something else?
