I was experiencing the dreaded occasional miss/stutter until it got so bad the the check engine light came on. The mechanic at work scanned the car and it came up with some odd code, sorry I didn't ask him for it. His reader/computer, however, gave him the info that it was intermittent power loss to the ecm. We searched around and spotted some corrosion around the positive battery terminal and thought that I should take it home and clean it thoroughly. I did that and as I was poking around I found another red wire with a blue stripe and a red plastic insulator on the starter relay. I think that's what it is, a black round thing where the red battery wire runs to located on the far right looking into the engine bay. That wire was completely covered in greenish crud and loose. I cleaned and tightened it, put in some silicone grease and all seems well, at least for now. It might be worth looking at. Maybe now I can get past emissions.
