Car acts like its missing.
My borther has an 89 IROC, 305, auto, and the car runs like it is missing. We've checked the wires(replaced), checked the plugs(replaced), checked fuel pressure(40psi), and replaced the fuel filter. Nothing seems to help. If we start the car it runs like it's not firing on 1 cyclinder but everything looks like it's running like normal. If he drives the car eventually will die but will start back up.
Any suggestions at this point would be appreciated. Thanks.

2 bad injectors. I ran ohm readings and #3 was at 8 ohms and 5 was at 1. After replacing #5, the car ran 200% better. Will be replacing #3 in a week.
