Hello guys new to the forum and starting to have some issues with my 1995 Grand prix DOHC 3.4L.
Ok so I bought this car for commuting back and forth to work car is spotless very clean with 150k on it but its been a problem since I bought it.
So when I drive it it runs ok I can drive it for hours but if i let it idle for more than 2-3 minnuts the thing will start to run rough spit n sputter and then die, and when it dies it will not start intill it cools down at least 1 hour and then it will run fine. I checked the shrader valve on the fuel rail and nothing but air comes out after it dies even while cranking only air will come out, So could it be a fuel pump I changed the fuel filter but that did not help and its not overheating? any ideas would be great thanks
