Sounds like you have provoked the RUST monster... Would check out the condition of your fuel tank first...Z fuel tanks are real bad about rusting inside. Let us know what all you find in there...pictures...etc...etc.

Did your car sit for a while before you bought it? If so, you're lucky to get four months out of it. Mine sat for four years and really wouldn't run right until I dealt with the tank. The EFI cars get it a little worse than the carbed cars but in either case you'd be better off cleaning out the tank.
