2001 w/Computer or Wiring Problems...
OK, it all started out with what felt like a TPS problem. From idle or off-idle she would stumble or do nothing at all and suddenly send the tires up in a blaze of smoke. A couple days later she started sputtering and missing badly. Then, for no apparent reason she would straiten up and run like a champ.
I found several articles on the forum about ground wire corrosion which helped quite a bit, thank you to those guys. But she's still acting up and throwing codes. Below are several days worth of codes. After recording these I cleared them.
While checking and cleaning connections I unplugged the main computer as well as the one below the carpet on the passenger floorboard. After reconnecting everything including the batter it wouldn't crank at all. I eventually disconnected the harnesses from the computer under the passenger floorboard and it finally would crank and start. I drove her for a few days but when I parked her yesterday she went back to that computer thing where she won't crank at all.
Idea's?
She's dead right now and I'm getting the itch.
