So I'm sitting in my driveway trying to figure out my stutter problem out. Guessing it has something to do with me screwing up my fuel rail, putting in a bored TB or replacing sensors I wasnt sure that were INOP. Anyway so the mirror shakes and it annoys the living crap out of me when I'm stopped at a light or just sitting with it idling (around 750). So I decide to give it some gas and get it up to 5k RPM and remove my foot from the pedal. The RPMs come down to below 250 and die. Anyone have this issue before?

Check the iac. Mine was acting weird so I replaced mine. Engine runs better now

Cool thats one of the few things I havent swapped out yet.

Sometimes you can get away with cleaning it. If you get some carb cleaner you can clean the carbon out of it but if the motor is bad then you should probably just replace it

I tried cleaning it when I swapped over to the new TB. Im just going to replace it see if it works. I have a new fuel rail on the way hopefully that will solve some problems too
