(wink-wink.. nudge..nudge). The MAF could be bad. O2 sensors don't jerk the fuel trim around enough to cause misfires, so I'd rule them out. Also can't see all 4 coil-overs being bad to cause random misfires.

Let me see what I can do to get someone to loan me a better scanner or just pay someone for the diagnostic. I'm with you on the coil comment because the spark plugs are white. It's obviously fuel related and not the coils. What do you think about the TSB that states that you have to replace all 4 injectors & reprogram the computer ?
