where did you wire up the mapsensor ? its not part of the engine harness its on the firewall on passenger side. connect vaccum to stock location map sensor and use that instead of the d16z6 map sensor on TB

i am using a completly diferent map sensor. im not using the one on the tb or the one on the firewall. i think ity has that gm 3 bar one . it has 1 red, 1 black, and one white wire. there is no plug plugged into either factory map sensor.
