what my question is... has anybody ever seen this many codes. and i believe its my ECU that is bad... somehow? the weird part is the truck runs great! just the CEL comes on have 30sec of running.

when i have looked at diagrams of my ECU (part number-89661-35110) practically all of the codes that i got were listed on the diagram.

ECU? are they all real existing problem? or is a half Shark half Python somehow get inside my ECU and playing games with my <3?

serious help!

2. No, I never have. I find it almost impossible to believe truthfully.

3. Codes on the diagrams? I don't know which ones you mean, but you kind find them all here. http://ncttora.com/fsm/87-4Runner/to...4runner_88.pdf

4. If the truck runs great with that many codes, I'd start thinking it was the ECU too.

5. Cool! Now I've got Dr. Octagon Halfsharkalligatorhalfman stuck in my head at 7 am.
