I have seen a lot of different discussions on this error code. I started running rough and happened to have a meter on me. I got this code. Made it to where I was going. Sat there for the day and when I went to restart it, it went on fine. Reset the code and drove home. Next day I picked up a coil in anticipation as I did not see any obvious wire problems. It crapped out again so I replaced the coil. It ran great. Went home, ran perfect. Started up the next day and went about 1/4 mile and started running rough. If I stop, turn it off and restart, it runs fine for a while. Also, if I turn it off while I am driving and turn it on again, it runs fine for a bit. I am leaning towards the ECU right now, but am also going to do a more thorough wiring check. Suggestions?
