Yesterday I got in my car and went to work and it seemed to be running fine. When I went to leave for lunch, it was jerky and almost acted like it was missing at low RPM's. The service engine soon light was flashing at me. I stopped at home before I left to go to a mechanic, and when I got back in and started it up, everything seemed to be fine. After work I was stopped at a stop light and put it in neutral, when I shifted back into drive it didnt do anything for a couple of seconds. It just sat there. Finally it went into gear. I scheduled it to have the transmission flushed and have a new filter and fluid put in. I hope this fixes it. Any thoughts?

ur misfire is either the plugs, or plug wires. Or your MAF sensor wires might be damage. or the MAF unit could be dirty itself. When my MAF plug broke a wire inside of the harness, my car idled like crap, then runs fine, misfires at times.. Cuz the wire was making contact on and off. It took me 5 months to detect the broken wire in the harness.

Sounds like a misfire or a downstream o2 not reading right
