Listen folks, not to take away from any other site, not trying to promote anything other than sharing info, but this particular site has the best detailed tech info I've ever seen and the site owner will help you find and fix anything. He knows engines as well as anyone I've ever dealt with. http://forum.grumpysperformance.com/index.php
I'm not trying to step on toes, just sharing a great piece of info I discovered.

 

Hey, good find!!!! :)
