Missfire is getting worst, watching the SG2 on way home, GPH went to 0 or real close at times even wasn't missing. TPS doesn't seem to change much from 25 at idle with limited sample of data seems like 35-38 on tps is where it cuts out. I'm leaning towards MAF, only if my other cobalt was closer I could swap and test. Did a couple 2nd gear to 6000 rpm pulls and it no misses, also did 5th gear up hill 1300 rpm to 2000 (55 mph) again no misfires.
