I did a log and uploaded to pidfusion.net to compare to other similar trucks. I'm hoping that someone that works on these regularly (like Clinebarger, etc) can comment on anything they see that's out of line. Unfortunately I can see comparing to the baseline (60mph cruise) everyone else was in overdrive at 1500 rpm. I usually leave mine in 3rd because of all the weight in the back, trying to squeak another 100k out of the 4L60E.
Log is a couple minutes at idle and a couple at 60mph sort of flat ground, slight hill towards the end.
Only driveability issue is occasional misfires on throttle tip in (if I'm not gentle enough) pulling away from a stop when it's completely hot. Possibly the coils are getting tired, but I don't know. Everything is original (that could affect obd data) except the plugs and it's 240k miles.
What do you think?
