right but would other ECU's hook up to the harness? all plugs have been extended and converter properly so lets rule out the harness for now, what else could the problem be? just the MAFS or could it be the ECU as well. The car will idle most of the time but the throttle response sucks and if you open it too fast it will bogg down and stall. I check all the coil packs for power and there all good.
