I need help form all of you pro/home mechanics out there...
My 1993 Oldsmobile Cutlass Supreme T up and died on me on Sunday. It started vibrating badly and stalled after only running for ~5 minutes. I checked to see if the exhaust was clogged but it seemed to put out plenty of gas when running, but a lot of black soot as well. I pulled the spark plugs, and they were fouled as well. I will clean them when I get a chance, but I am wondering why I am running rich in the first place.
The plugs and air filter are only 6mos old, and the air filter is clean. The air intake is also clear, and the spark plug wires are brand new a couple of months ago. There is no check engine light, so I believe the O2 sensors are fine, but will check them with a volt meter when I get time.
I am starting to lean toward either a distributor problem, or excess fuel pressure. My last oil change about 3 months ago ended up cutting the wires to the fuel pump (whatever idiot at GM decided to run those wires right under the oil filter.... grrrrr.... one wrench gets away and YANK!) There is a small possibility I swapped the wires on it, because the color coding was funky, It looks like this had happened a couple times because those wires had been spliced a couple of times.
If anyone has ideas, PLEASE let me know, I had rather do this myself than take it in for a repair that may cost more than my vehicle is worth...
