The car started shaking, rough idle, sputtering. It was bought from a private owner, it ran good the first few days. Had a tune up, a few days ago, and this morning all of the weird idling started. Took back to Jiffy Lube, to find out the coils had silicone on them. My question is, if I change the coils and spark plugs will that be resolved, or does the car need a new engine?
