Does that ground connect to the firewall above the vin #? If so, it was disconnected but I reconnected it and it made no difference. But thanks for the pic.

so is there only one ground for the ecu and is it at the firewall by the windshield wiper motor.

I've also heard the position of the MAF may contribute to the hesitation. For example, some of the intakes require you to twist around the MAF from its original position like the BONEZ.... Also, I heard an extra ground on your fuel pump may help.

i think i might have an intake leak or a bad vacuum line because i can hear air when the engine is running i think i might have might have a bad intake manifold gasket. would that effect anything
