I had the crank sensor relearned. I got the BAFX bluetooth thing, I got car gauge pro. I set the CMP retard to 0. It still had a rough idle so I decided to do a compression check, which I probably should've done to begin with. I didn't check cylinder 3 or 4 because I didn't want the struggle. This is what I found out cylinder 5,2,6 had 160 psi, and cylinder1 has 120 psi . So I guess I have a compression issue on #1 cylinder, whats causing it, I don't know. I still have p0301 code, as for p0300, I'm not sure at this point. Where do I start? I wish I would've known while I had the engine out. Bummer.
