Re: Mixed plug wires?

I meant on the plugs themselves. I have seen people, myself included, connect the #5 cable on the #7 plug and vice versa.

Re: Mixed plug wires?

Re: Mixed plug wires?

Looking at the way the Vac Advance was clocked, I would guess a tooth off is at least part of the problem.

Re: Mixed plug wires?

As far as I know the mileage is correct on the car. I cannot thank Albert enough for tackling this challenge. As I have mentioned before, I had this car to numerous "Corvette experts" and none of them picked up on these things that Albert found in the short time he's had the car.

Albert forgot to mention that the distributor was not installed correctly; when he brought the #1 cylinder to TDC the rotor was pointing to the #8 cylinder instead of #1. The plugs were gapped at 42 instead of 35 which is what Albert said would have been recommended.

I can't wait to see how much better she runs when I get the car back. After 8+ years I'll finally have the car I had hoped I'd have when I first bought it.

Cool that you're getting the help that you need. Albert rocks! [img]<<GRAEMLIN_URL>>/headbang.gif[/img]

I cant take all the credit, my buddy Joe is the driving force on the diagnostics..he's a sharp cookie..seen it all [img]<<GRAEMLIN_URL>>/grin.gif[/img] ..he may chime in here later.

Re: Mixed plug wires?

OK corvette guys..whats with the tach drive cable..is there supposed to be a 90 deg connector in the back of the distributor for the tach cable??..I see they make a aftermarket one but cannot find anything on a OEM one...sure could use one here!!....Mosport you out there??:)

Re: Mixed plug wires?
