1991 Isuzu Trooper 6 cyl Four Wheel Drive Manual 175000 miles

I have a 1991 Isuzu Trooper V6 5 speed manual - It started idling high a few days ago and now It floods itself everytime I start it. I have checked vacuum hoses. They look fine.
I read that I need to reset the ECM codes.
I cannot find the ECM and the EMC fuse.
Does anyone out there now where it is located?
It is not in the fuse box.

Thanks

Undo your battery for 5 min or so. It sounds like its the throtle positioning sensor went bad its located on the throtle body. I ruined mine once when I degreased my engine. Your ecm is located under your center console and has a jumper wire unhooked to check codes
