It just stalled
I came off the interstate and hit the brakes pretty hard and the engine stalled. I cranked it over and it backfired out the exhaust then started back up with a raw fuel smell. It has never, ever done this before. I am puzzled. It drives normal the rest of the way home. I have a brand new GM opti, new Taylor wires, new, MSD coil. I can't imagine what would make it stall. Recently, I did replace a lazy O2 sensor and the milage shot up from 18 to 20.5 but, that 's a good thing. Any takers on where to look. I checked the coil wire, and connectors. I think I may have caused the raw fuel problem by mashing the pedal, I thought for sure it was going to be a tow home but, it fired back up after the third crank. Go ahead, give it your best shot.

Well, today and it wouldn't start at all 
I re-checked the coil wire and discovered the opti side of the wire had loosened up (the boot was still attached to the opti but, no metal contact) I pulled it off and found a ton of carbon build-up. I guess this has been going on for quite some time. I cleaned it up with a steel tooth brush thing and shot a little compressed air and WD-40 on it, then used my new 12 inch off-set needle nose pliers to hook it back up right. Well, it fixed the problem. After ten or so miles of driving, I could tell the plugs had burned clean, I had better throttle response and a little more top-end 3 MPH or so in the 1/8th. I guess it would be a good idea to re-check that wire from time-to time. Thanks for the responses. (no-code BTW, I checked that first)
