Key on/Engine off, wot on accelerator. Should I hear a constant humm or buzz from the throttle body? Every once in a while the butterfly will twitch. Seems odd.
Ok. It’s been on for a month or so but I’ve heard people say there is a relearn process. The TB had a tag saying something about it as well but no specific instruction. Was just curious.
But the biggest thing about it all is the fact that only once it’s warm it begins to run rough. Prior to that it’s fine. Going to focus on the wiring for the ETC first and see if maybe once the wiring is getting warm maybe there’s a wire with an issue.
Yes, this is the replacement PCM. So either the first PCM was either good and the problem was certainly something else. Or the culprit for the first failing PCM is causing this as well. OR the problem really isn’t the PCM at all still. I printed off a bunch of wiring diagrams and I plan on...
That’s about where I’m at. I’m just so baffled as to it running perfect until warm, and then when it does go to etc failsafe it runs rough, but under throttle it clears up. I talked to the previous owner and he said he had the O2 sensors changed at one point and he said the symptoms sound...
