had buick dealership look at it and thats what they told me

were are the oxygen sensor located on a 1995 riviera buick

I have a 1990 Lincoln with a 5.0L engine. It would not start. I tried starting fluid and still nothing. Checked the fuses ad computer modules under the hood, all was good. Hooked up a timing gun ad it didn't light. Took the distributor apart twice and the same result, no spark. Replaced the primary wire with a spare from my shed. Still no difference. Cranked it one more time, still dead, then the timing light finally lit and the engine started a second later. Obviously, I have an intermittent condition. My experience in electronics is they are the toughest to find. A complete failure is much easier. Sure much harder working o cars these days. The computer and smog controls call for so much equipment. I will soon be replacing this car as I am certain it doesn't have much time left. 278,000 miles without too many problems other than power windows, power seat and air suspension. Open to suggestions as to where the problem resides.

I have detached two wires, removed one bolt and loosened a second bolt in which there is not enough clearance between the alternator and the car to remove. I can wiggle it around but still cannot remove it? I do not think there is a 3rd mounting bolt, is there something still attaching it or is there a trick to getting it out?

Is there any special way to treat the lines ???

seem like it is not getting any gas

do you have a picture of where the pcv valve is located. we are trying to change it to pass emissions

none to add

The car is giving me a trouble code for "Exhaust Gas Recirculation Insufficient Flow", So I put seafoam in the intake manifold vacumn hose, and in the gas. I reset the codes and drove around a bit, and the light came back on, so I ran the code reader again, and it gives me the same code. What are the possible causes, how common is each, and which component should be checked first?
