Typically 97 automatic bird with p0100. Fuse keeps blowing after going into closed. I check my o2 connections, no melted wires, and cant seem to find shorts. My rears are not even there, physically. NO cats, no 02s. Always ran great for 2 years, always had 02 codes but thats it, ran high 11's.

Code and problems came instantly, heavy heavy bod, rich as hell, like 1/4 tank to go 30 miles or so. Bogs, then lights up and hauls butt.

I check pink to black 12 volts, black to yellow 4.6, pink to ground 12 volts, and ground to battery 12 volts. Wiggle and no change.

Any other suggestions other than PCM replacement?
