My 1993 Pontiac Grand Am 3.3 liter V6 with 115,000 miles on it stalls out and will start sometimes and not start other times. I have recently replaced the fuel pump, and it is getting pressure, it is also getting spark. When I do get it to start I have to keep tapping the gas petal to get it go stay running (rough). When I go to drive it I can not hit the gas more than slightly or it will bog out completely. Check engine light is not on. I scanned for codes anyways and came up with only a diagnostic code. No others, and I checked for vacuum leakage. Thank You for your time.
