I have a 90 Chevy Lumina 3.1L. I changed the fuel filter and I have no codes from the ECM. I tested the fuel pressure and it is within spec. The problem is, it idles fine in park, drive, or reverse, but when you give it gas, it stalls. It does this whether or not the air filter is installed, so I know it is geting enough air and fuel, and like I said, there are no trouble codes when I check them.
