What exactly is KR and how should I read it with OBD 1.5?
Hey, my 95 still isn't running too well and it only gets bad when i give it alot of throttle but runs fine otherwise. all vaccume lines have been replaced and it had a tune up. what could be the issue? i have no SES light so i can't read any codes. I was reading another thread and saw that it was about KR and how it increases with boost and i was wondering if it could cause an engine to run like crap. only issue is I have OBD 1.5 and am not sure what to do. my buddy has HPTuners and can monitor cars, but he said it may not work cause its OBD 1 with an OBD2 style connector. any ideas on how to check this and what knock retard really is or does to the driveability of a car?
