Question Please look at this autotap log...

Log File

Major Mods:
LT4 Hotcam
PCMforLess hotcam tune
Comp Cams 1.6 rollers
Crane 10308 spring kit
Vig 3200 stall
MAC headers

Car has been running a little off lately. I can't pinpoint the problem b/c it comes and goes. Basically one day it will tick really loud and run like crap...then the next it doesnt tick very bad and runs great. This log is from today when it was running very bad. Also to note it was 40 degrees outside and the IAT was reading 86 at one point if that matters. I have checked the pushrods, changed the plugs and wires....problem still persists. Any help is appreciated.

I Assume this problem persists during normal driving since you never tested at WOT.

Wow, #1,35,6,7 pretty much all of them seem to have quite a few misfires.

Is this a 96 or 97?

Are you throwing an SES light?

When was the last time you replaced your opti? Or even your Coil?

Car is a 97. Coil is MSD and about a year old. Opti is also around a year old. I am not getting any codes either not even a misfire code.

Run a Table on your knock counts. Id like to see if your knock sensor is picking up anything.
