RevMS2v3 engine running erratically. Was perfect 2 days ago. AFR/RPMS/MAF all over!
Sorry for the long title, but was trying to be descriptive. Two days ago my car was running amazingly and it's just been in the garage till today. This afternoon I jumped in it and right as the RPMs started to settle like they always do, the engine stumbled real quick and then just quit like someone shut it off.
I tried starting it a few times while I was checking things over in TS. Sometimes the car will start normally, then, stumble and shut off. And other times I'll start it and the RPMs swing wildly. AFRs are all over the place and it's basically not operable.
I pulled the battery for a couple minutes to see if that would clear the problem and it seemed to, but I took the car for a short drive around the block to check it and after running fine for a few minutes, it cut out. I had to turn if off for a min and restart a few times to barely make it back to my place.
This log is after having the ignition off for a few minutes, start, run, not touch the throttle and let it run it's course. Started a second time and let it run it's course.
After looking over the log, I noticed the MAP looked weird. Moving around a lot and 80kpa engine off, all kinds of crazy. Thoughts anyone please?
TLDR: My MS is going crazy and I need help. Log/Tune included.
MS2v3 reverant built. 2004 MSM regular install. Nothing crazy
Thanks for your help.
