Hi All.

I have rough idle and no codes. Anyone care to suggest interpretation of the data linked here? I would appreciate any help!

Thanks, Mark.

P.S. I note the TP appears to have dropped a tick or two while accelerating or steady.

RPM TP
763 20
807 22.35
1537 24.31
1832 24.31
1943 21.17
1955 24.7
1929 24.7
1964 24.7
928 20

I've had these go bad on other 5.0's without kicking a code at all.
