Dies when i let out of the gas

[Sinister86]

My car has been acting weird for about 2 months now
first it threw a code 34 so i got a new maf and went with the ls1 maf and translator. now it just is faster when it wants to act right and still has problems. it seems to want to die when i let out of the gas and sometimes at idle, altho resetting the screw has heeded that off somewhat, what else could it be? tps is fine at .042

dies

Maybe a lazy IAC or not set correct

I second the IAC. Before you set it, take it out and clean it. Then do a search on here on how to properly set it. I bet that will solve your problem.
