Thanks Guys, sorry I was thinking out loud.
Just to clarify a couple of things: The car doesn't stall under hard braking, but almost. I overlooked a potential fuel problem. Thanks I'll check i out.
The #8 plug isn't fouled, but it's darker than the others. I don't think it's due to a leaking seal or ring. When I first installed the engine I ran a PVC without a baffle in the valve cover... DOH, the plug was fouled then.
Anyway, I think I'll switch the pvc and the v/b connections.
Question: Is there a simple test to see if the brake booster has gone "bad"? Under hard braking I have to press pretty dang hard on the pedal. Is that normal?
Thanks. Jon
