Bizzar - when I got home yesterday it was up to it's new tricks by reaving, it had no rhyme or reason to when it would rev, and when it would idle at normal speed. I started looking for leaks and figeting around with things until it started to sustain the higher reving speed, only to calm down and get back to it's original idle speed. Strange. I let the car idle for a while and it didn't revert back. I doubt the problem fixed itself, but I'm hoping it did **Thumbs crossed**
