I'll assume you have a code reader so you can recheck if the P0301 has turned into P0304.PapaVanTwee wrote:I have the new plugs in, and it seems to idle smoother. I also rotated the coils, moving the right most coil (the #1 cylinder?) to the left most (#4?) and shifted the rest to the right. My plan is to do a pressure test this weekend. I am also going to do an oil change, and may do a Seafoam flush of the oil before the change if the pressure test is okay.
No rotten egg smell today, but the MPG went down below 28 after a promising 37 last fillup, and 29 the first measurable one. There was more city driving, however.
Found two good articles on diagnosing and fixing this problem. Thanks to all for your current help, and I hope tomorrow and this weekend will give us some better clues as to what this could be.

3) Sell and get something elseSalsa Guy wrote:Any type of chemical treatment won't last. Running that thick of oil will cause other issues in the long run. If you are getting good MPGs I wouldn't bother with doing anything until it dies. Re-building the engine with out the knowledge or tools would be a mess.
3 Options
1) Buy a used engine for $700-$900 and have it installed for another $700-$900
2) Have yours rebuild for $1400 to $1800

I'm getting the feeling I'm going to have to fix or sell it.

I go between that and fixing it. Depends on how much I feel about keeping it. Because it's still a blast to drive.Nasmfell wrote:PapaVanTwee wrote:Did a full day (instead of a few minutes) of flush last Friday, drained the oil when done and soaked the pistons while it was still warm.

You're leaning on selling aren't you?
