Need help with surging
I recently started experiencing surging in 1st and 2nd gear at lower RPMs. It almost feels like I suddenly forgot how to drive a manual.
I just replaced the spark plugs with one-step colder plugs, initially gapped at .022 and then tightened to .020, but I didn’t notice any difference between the two. I’m also running brand new coils and a new LPFP. I'm seeing no codes in MHD.
Does anyone have suggestions on what I should be logging to help diagnose the issue?
