P0306 code

[aidanm]

Hi all,
So I thought I had solved my p0306 code with a new wiring harness that I got from deadjeep. It came with the harness that comes with the drivers side and the other harness for the passenger side. I just put in the drivers side because I figured this would solve the problem. It ran great last night but after driving it for about an hour and getting gas it started idling rough again and then the p0306 code came back again. Any ideas? I’ve already done a leak down test and compression test and there were no issues there.

How did the PCM connectors look?

Have traded plugs or injectors from say 5 to 6 to see if the code follows?

The pcm connectors looked clean, no gunk or corrosion or anything. I’ve swapped plugs 3 times and swapped #5 and #6 injectors and no changes.
