Yesterday I put in a set of Autolite Plantinum2 with new plug wires(Xact), Today I put in a brand new Bosch O2 sensor, I checked the ohms on the coils today also(and swapped them to the bonneville) They were all in spec with the TECHINFO how-to. Also last night after it was dark I, I pulled the plug wires of each coil seperataly and seemed to me to have a nice arc between the posts. Sevice Engine Soon light is still on and although it runs a little smoother then before it still runs like crap. I pulled the front three plugs today and #6 was sooted up again.
Before Thrusday the car ran fine, but would hesitate slightly at about 60mph sometimes. Then thrusday morning I had to push the gas to get it started then it ran fine, after work same thing, but when the wife went to take it later that night is when all this started.
I think I have a MAF sensor, at least that is what it looks like to me, and according to Advance Auto'* website they have some listed for my car.
When the car was scanned he said the only thing it said was 2 cylinders were not firing(before I changed all this).
Car is close to its mileage for an oil change, would this make a difference if I changed it, also the rest of the fluids where changed early spring.
