Hi guys, first time poster, i have a 2004 NP 3.2 DID. Just replaced the head and now i have an issue with the air temp sensor. If sensor is plugged in car runs very rough and wont rev properly, unplugged car runs normal, just purchased a new sensor from Mitsubishi and still the same problem. Took it to local diesel mechanic and he plugged computer in and no codes and it also has him stumped. Any help would be greatly appreciated
