Well it's thowing the p0102 code for low input on MAF.. all the wiring looks good and i tried a new MAF sensor but that did not fix it.. All i can think of now is a bad PCM.. when i start it and put it in gear and push on the gas it hesitates for about a second and then takes off.... and it seems sluggish when i step on it, it kind of feels like turbo lag...
