new problem with the GT

[justin11045]

after having an entire new engine and computer put in my car now when i put a little more gas than the average needed for driving in 1st or second my car jerks violently dies ( like i stalled it) and the odometer goes to dashes. i blew the pcm fuse twice now once in california when i was with foxman and again yesterday. i am dumbfounded on this problem and do not even know where to begin.

I'm guessing you have an exposed wire somewhere in the car that is grounding to the chasis. Since the car is bucking, I would start with the MAF and Fuel injector wiring. Another comon spot for these problems is in the O2 sensor wiring as it passes from the engine compartment to the transmission tunnel. A pinched wiring harness is my guess. You just need to find where.

i did a little more research after i posted here and found exactly what CWO said. so i checked the maf, it looked fine till i looked at the wires leading to the bundle. one of the wires was grounding to the chassis so i taped it up and now it runs great

And your car didnt throw any codes with that issue?

no. just the p1000 from the batery being dead for awhile needs to relearn i guess.
