The powers to be do not like it when you post the same thing in more than one forum. That being said, have you unplugged and replugged all the coils a few times to clean up the connectors?Trying to solve an issue with vibration while idling in Drive or Reverse (sometimes in Park/Neutral). Problem described in linked thread. I am thinking either injector issue or a coil but not sure.
Here is the link to my other thread.
Not sure where to go next. I did order a PCM tune from PCMforless over a week ago but they have yet to send it out. (they were waiting for more cores). I was hoping a new PCM might help but since this vibration thing just started about 2 weeks ago I am thinking it won't. just searching for any info.
Any help appreciated.
