Ok so I was driving my car yesterday and it was driving ok and all of a sudden it started to miss. It has a miss through any type of load and set the idle down to like 600. I had to replace the o2 sensors and I bought two used ones off of here for little to nothing, I knew i was going to need one extension so I got one along with the two sensors. Got one installed and then found I needed another one so I drove it with the one new one and the one old one and it drove fine. I finally got the other extension and put it on. It drove perfect for about a day or two and now it will miss with any type of load. Im pretty sure its the o2 sensor but wanted to check what you guys thought before I went ahead and bought a new one.

Ok so i pulled the o2 and cleaned it with sime brake cleaner and no change. Then i unpluged the maf and it drove fine but still had a smallllll mis. What does this mean?

I had the same problem and I had it checked out and they told me I had 4 fuel injectors going bad and they didnt start acting up until the engine was warmed up it could easily be anything I would start with checking the easy things first but that was my experience w my 94 formula.

So why does it clean up and quit missing when the maf is unpluged.
