Alright latly i noticed my engine is not idling smoothly. When i start the car up it takes a while for the idle to get to where its suppose to, itll start at like 1k and work its way down to normal 800-850. But i think thats normal. But after the car warms up and i idle, its sits at the right rpm,800 but the engine doesnt seem to be running smooth, theyll be an occasional small vibration, its not extremely noticable but it just doesnt seem like its running smoothly, it may be running normal but im not sure. Idle rpms are fine so i dont think its my volant, and i checked to make sure all the connections are tight. Only other problem is terrible 19mpg gas milage, so maybe the spark plugs are going.....even though i only have 14k on the car. Let me know what you guys think, i was thinking about getting new plugs anyway and seeing if it would improve the milage. Let me know which kinds i should get, and how much they cost. Thanks guys.
