Engine at idle seems to pause and excel but never stops or quits. I just changed the spark plugs. Not sure if this is a misfire? While driving I do not notice only in Park or while at a stop light. Any help is appreciated. Thanks

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

1. Defective spark plug.
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. MAF sensor
11. IACV
12. TPS sensor
