So after I fixed my fpr problem things were running great. Then on my last trip I was showing off and man... the car started breaking up pretty bad after 4-5k. Put the logger on it and sure enough, shit ton of knock and the rear seems to be running lean again. However, this time, the fuel pressure stays rock solid.
I pulled the plugs and checked compression. 150,148,155,155,150,152 (1-6). I noticed plug #4 was much whiter and was flaky. I would assume this is the culprit cylinder.
(#3,4,5)
Clogged injector? Something else? Curious if anyone has an idea of how one cylinder going lean would affect the afr after all three mix. Thoughts?
Thanks,
Antoni
