Hello All, i need your help. i have a 2.5L that I cannot make run with the MAP sensor plugged in. I have tested the MAP sensor and it reads good. i have tested the MAT, Engine Temp and Idle Air Control Motor as well. Replaced the TPS, O2 sensor and the ECU. i have checked for Vacuum leaks and have come up with nothing. it runs better with the MAP unplugged from vacuum. I am running out of ideas. Any help would be greatly appreciated.
