May 86/87 Toyota Dolphin 21' 22RE EFI Hi All, Now that I'm in one (dusty out in the middle of nowhere) place for a while, I can attend to the nagging issues that have attended this journey. The check engine light, quiet up until Tucson, is now flashing in bezerk spasmodic patterns. It is time to hack the computer and get a good reading - NOT while I'm try to drive in high wind conditions. Linda, you mentioned this article http://www.4crawler.com/4x4/CheapTricks/TroubleCodes/ I did find that, and I have the two little diagnostic yellow plastic cylinders on the sidewall, but it does not say where you stick the ends of the hair pin. Just randomly one into one side and one into the other? I am hesitant to stick metal into live electric areas with which I am unfamiliar. So here are my little yellow doohickeys. They have specific plug patterns each. Where should I poke 'em?
