Half way through the 2nd day of this last race my engine started to sputter in the high RPM ranges. 5k+ After service and the engine cooled down it came back to life. About 6 miles into a 10 mile stage the high RPMs started sputtering again.
Then it kept getting worse because I had two 12 miles stages right after that. As of right now, the car will not idle, if I give it gas the car runs fine even into the higher RPMs until it heats up. I thought it might be spark, but i'm getting spark at least just checking it in my garage. I also did a compression test and the numbers are good 190/180/180/180 The engine is a 3sge.

QUOTE (kurt95gt @ Jun 3, 2012 - 6:12 PM)  Clogged fuel filter or a vacuum leak? Hmm.... vacuum might explain it. Obviously explains the idle, but wouldnt explain the upper RPM range, until I remembered that the 3sge VVT system is activated by vacuum. I'll have to go over all the vacuum lines tomorrow. -------------------- -93 Rx7, Turbo 6.1L v8, 725rwhp/760rwtq
