the following has been done so far
-new harness- from ecu out
-tried swapping ECU with another
-new TPS adjusted correctly-MAF voltage is also correct(does not exceed .09 or .9, whatever it is)
-new plugs(checked cap and rotor, they are new, wires were installed at the same time)
and let me add the following, this kid cant keep his hands out of the car, ill fix something he gets in there and F's with the car and he doesnt know a dam thing about cars
My car did the same exact thing when one of my wires was going bad
