2004 Grand Prix feels like it wants to shut off after a few seconds when i turn it on. Feels like a rough idle when I'm on PARK or when I wait for the traffic light to turn green. So far it hasn't turned OFF yet.
I have cleaned the throttle body because it also feels like I have a low RPM. When I accelerate I don't feel the full force of what it should be. It feels like if it accelerates slow and then it goes normal after like 4 seconds with gas pedal on. It goes away after a few miles. But when it cold engine and drive it anywhere I feel slow acceleration. Any help is greatly appreciated.
