learn something everyday. I guess that is why some cars ping on 87 with e10 and won't on regular gas.

My dad's stang won't run on e10. he can fill it up with regular gas and the car be fine. If he stops out of town and gets the e10, he said he barley makes it home. Not really sure why but, it is true. Course with 2 burnt valves and 340k on the motor I guess he can expect problems.

Vac leak behind the dizzy? I didn't even use the gasket there, just a heavy bead of silicon.
