Battery voltage high?? May wanna look into that one. Could cause some interesting problems. I don't *think* the O2 code would cause it though, that's the rear O2, and it basically is just to monitor the catalytic converter. ABS codes certainly won't.

 

I'll look into it tonight.. thank you for helping me.

 

Get the alternator tested.

 

Check the 140 amp fuse, might be loose

 

Alright, update.
These are the parts I just recently changed.
Bought a brand-new distributor cap and rotor, brand new catalytic converter, new spark plugs again and a IAC.
Cleaning the TB and replacing the Iac has fixed it randomly dying while shifting or coasting.
My Father said it sounded like a piston or valve sticking but it wouldn't just clean itself up.
I have yet to check for any vaccum leaks or shortenings. I fixed the battery code I was getting and still nothing new.
It quit backfiring when it chugs and now will chug until from 45-50 until I get down to 10-15 and randomly start accelerating again and will start over after 2-3 miles. Sometimes I'll get lucky and only experience a single chug there and then another on the way home.
I would extremely appreciate if you have any information that I'm missing, anything that could help me track down this irritating problem I've been experiencing for years.
