It started with all 4 O2 sensor codes. After some checking found that the heaters in the O2 sensors aren’t working. So I ordered a reman ECM programmed to my VIN. I installed it and it ran horrible. No TPS signal, no alternator charging, traction control blinking, no coolant temp signal and the engine idled at 2,000rpm. Obviously I though it was programmed wrong. I sent it back and they reprogrammed again with me obviously checking the VIN multiple times. I received back the second time from the company and the exact same scenario. So I sent it back and went to a different company. I received the new reprogrammed one from company number two…and the same scenario happened. Obviously by now I’m Here asking what do you think is the problem with me being able to get an ECM programmed correctly
