disconnect your battery and step on the brake pedal a few times to clear all the charges out of your system. then after a few minutes reconnect the battery.
Ok, you need to carefully follow these directions in order for you ECU to reset properly... disconnect the neg terminal, then mash the brake pedal in 5 times(no more, no less).... then let the car sit for 30-40 minutes, then unplug your MAF sensor and let that sit for 10 minutes.... now after all that is done....
go in the front of your car, do 5 situps, 10 jumping jacks and sing to your car what you might think his or hers favorite song is. then reconnect everything, get in your car, start it and then go beat the piss out of it for a few miles and everything should be reset properly! good luck
