Default Re: Who Can Diagnose THIS Total Mystery? Win A Prize?

It could be sticking valves, especially if you have bronze guides and have run some old gas.
Do this, hand crank (switch off)your engine and get a good feel for how good the compression is. Drive car, and when problem arises again, stop immediately and hand crank again. A noticeable difference in compression could indicate valves sticking. Weak springs could also contribute.

When do I get my prizes ??????
