I agree with ya...starting to think not related to distributor. But this possible blown power valve has my attention.
I've only had the car for a couple of weeks, and when I picked it up....it idled fine....been to the track once and dont know of any major backfire....but if you read one of my initial posts....I was experiencing alot of hesitation and engine miss under load (just off the line) and the engine would not get above 5000 rpm. Just in park....I can rev to 6000+ no problem. Thats why I changed out the plugs/wires/cap & rotor....just to get those components out of the equation.
We checked the timing at the track which was at 28 and moved that to 34....and although I dont think advancing the timing is at fault....thats the first time I noticed a problem with idle....really had to keep on the throttle a bit just to get it back on the trailer.
So if it were a blown power valve....how best to test this since I cant get it to idle below 1800?
