Getting even more basic here, have you verified that the battery
terminals are clean and tight and the cables are in good shape? I can't
count the number of times that's caused people problems. It gave me the
exact symptom that Sean is experiencing on an old Corolla I bought many

I would guess it's electrical in nature. Check to see if you have any
engine codes set. Could be a short somewhere - check the wires to the
distributor as they can corrode and short out. Check the AFM connection
Hopefully a code is stored that will help you find the problem. It
could also be a bad ground. Good luck!
