Compression is 180, no vacum leak.
Drove for 130 miles and it came back on, parked it for a day, went out and drove again with out resetting and it went out on it's own? Car runs fine, it's just that light.

That's kind of high of compression on a 4cyl could be carbon in that cyl causing it-recheck it wet and dry tests

Motor is complete overhauled, running 180 on all 4, has been checked numerous times, like I said this car runs great, it's just that stupid light. What is keeping it to come on and go off on it's own?
