Good day to everyone,I was wondering why I'm getting up to 16* KR between 1700-2500 RPMs. I can feather the throttle and get past it sometimes,or just nail it from stoplight to get rpm higher and hope the cops aren't around. Replaced knock sensors even though they were doing their job.
KR was so bad last night that I unplugged both sensors at the PCM and still had an occasional 1-3 KR between 1800-2400 rpm.
Anyone have an idea to what's going on? This thing is driving me nuts.
Still have PO171 and PO300,can't find any vac leaks and ltft is16 @ idle.
3.8 n/a has about 4k on engine,and lim gaskets were replaced around 1k ago.
Please help, thank you.
