I have a 2000 park ave. When I start it, it will run and then it starts idling rough and dies. Sometimes I can drive it a short distance and then it starts running rough. It backfires and just wont idle. I can start it up again and it may run ok orit might do the same thing

Do you
have the same problem?

Engine running rough or misfiring can be cause by the following:

1.Defective spark plugs
2.Inadequate spark/coil,defective spark plug wire.
3.Lack of compression
4.False air leakage.
5.Faulty fuel injectors.
6.Insufficient fuel pressure.
7.Contaminated fuel.
8.EGR valve that is leaking.
9.Oxygen sensors.
10.Throttle position sensor.
11.Manifold absolute pressure sensor
12.Mass Airflow Sensor
13.Idle air control valve

Note: If it doesn't apply disregard it-
