Ok guys, I figure someone on here might off suggestions. So I installed the Whipple 2.9 Stage 2 kit this weekend and have also data-logged WOT pulls with my NGauge and all looks good. I also performed my crank relearn while the car was at operating temperature. It ran a few 6.9s in the 8th mile at the track last night where I did my logging. The issue I'm having is, shortly after turning my car off, then turn the car one a few minutes afterwards, I get a random misfire code on cylinder 8 in the first 1000 revolutions(checking codes with my NGauge). It did not happen this morning when my car was started when completely cold and seems to happen randomly when starting the car. I have been clearing the code and seeing if it happens again after the first 1000 revolutions and it does not happen. Also this morning when I started it, it also seemed to have trouble finding steady idle for about 2-3 seconds, that was from a complete cold start but it did not misfire that time. I performed a crank relearn again this morning, went to pump fuel at Shells with 93 octane. Started the car pulled forward about 5 or so seconds after startup and got the random misfire on cylinder 8 code again. Cleared it and it did not happen on the drive home. I also seem to get a secondary O2 sensors rich code when it happens SOMETIMES and SOMETIMES at the same time as the random misfire in first 1000 revs code. I usually clear the secondary O2 rich code because I have vibrant defoulers, although that code happens more randomly. My question is, what could be causing that cylinder 8 misfire(also sometimes says cyl 6 along with cyl 8 sometimes) during first 100 revs code?
Thanks in advance, I tried to be as descriptive as possible.
