Ok I have a 3400 engine. When i start my car it bog s down and it sounds like it the engine is going to die then it shoots up to 1500 RPMs then goes back down to 400-500rpms but it stops once the engine is warm. I am wondering if there is something wrong with the fuel filter or a sensor but i am clueless. I have changed the spark plugs and wires.
