1976 Cadillac El Dorado Repair Question
Mileage: 120,000 miles.
How do I trouble shoot an engine skip in a 1976 cadillac eldorado 500
Answer
Did you replace the distributor cap and rotor? If not, did you inspect the cap for cracks?
I did replace the rotor and inspected the cap. I also checked for spark and continuity. I had thought it was a timing problem which is why i replaced the chain and gears. when piston 1 is tdc the timing mark lines up with the 0 on the scale but the rotor seems to be in the wrong place. when I put the timing light on it the mark is still at 0 but is supposed to be 6 degrees advanced. is it possible I skipped a tooth when I reinstalled the distributor or timing gear and chain? adjusting the distributor helps some but it still runs rough. Thanks
It sounds like you are a tooth off on the distributor. Line up the timing marks to TDC and the rotor should be pointing at the #1 plug wire on the distributor. It's really easy to be off one tooth.
Let me know what you find.
