My 1994 G20 with near 150k has recently been having trouble running. It all started when I changed the valve cover gasket about 6mo ago. I replaced it, the spark plugs, the spark plug wires and then gave it an oil change. After that I noticed while driving that the car was having sputtering fits, fits it wasn't having before i changed all that stuff.....so to make a long story short the car winds up dying, so i tear it apart and get the alt. tested its fine winds up being the starter, so I replace the starter and now it still wont work....the car runs for about 5min then it sputters and dies, then after it dies the only way to get it restarted is to hold the gas down, and the only way to keep the car running is to hold the gas pedal down......does this sound like a fueling problem or something else.....and if it is a fueling problem what are the steps i should take to check and change stuff on my own?
