Strange fueling problem...
Finally got the car to pull with no Knock from a stop thru the gears....or so I thought.
I am gettin no knock anywhere except the top of 3rd gear. From about 5500 RPM on up I am showing anywhere from 2 to 5 degrees of knock Usually 4.
Would this be a sign of a weakening pump or bad plugs? Or is it just a tuning issue? I have my LTrims at - 2 to - 4 all day long.
Last week at the track I was runnin 118 and it would miss a little at about the 1000' mark. Right where 5700 is in 3rd. I know this is a 120 mph car I just got to get rid of the knock.
Pulled the plugs and they read pretty good.
Can anyone recall a similar situation?
Thanks, Stu
