      I just didn't know what MIL stood for. Thanks.

      Wish I had the list of ground wire locations today. But I'll have to look them up when I get to work tomorrow.

      I wonder if the female side of the plugs are corroded. They weren't to bad but you never know. I also went through the under good max fuses and cleaned those up too.

      IIRC, 2 of the 3 PCM grounds go straight to the "pigtail" on the negative battery cable. The 3rd ground might go to the body near the PCM.

      I was thinking the same thing about the 3rd one. There's a ground wire right next to it. Haven't had a chance to check it out the underside of the eyelet but the topside looked good

      fyi guys (since i know a lot of threads get dropped dead with no update on the solution)

      my problem was just a bad ground. there is one ground on the drivers side fender well in the engine bay just rear of the rad/washer bottle for the pcm and one right next to the pcm they are both bolted to the sheet metal.

      edit: now she runs perfect
