We are haveing a problem with a car that has us a little stumped and i was wondering if there was any one out there that might see something in this file and data looking that we are over looking...the problem is at 191 kpa. The car is acting like it is blowing out the spark or it is hitting a rev limiter. We have played with timing, A/f spark plug heat range and gap( from .20 to .45 ) with no changes . Can Anyone
