You need to put your MAF back on. Get your stock computer with a proper chip for your setup. Disconnect the connectors and plug the original setup back up. Then I cut the wires near the heater, under the hood and capped them and pushed them back into the harness. I don't have the directions, so I don't know if that's complete. I think it is.
That's all that I can remember...it's been about 4-5 years. HTH
