ignition coils went bad?
i went to my mechanic this past weekend and without touching my car and just by listening to my description of the problems: rough idle, lack of power, and and car vibrates badly when i steps on the gas and when i turn on the air conditioner, he told me that i need to change the coil packs (ignition coils). can anyone confirm this? my car is a 95 c220 with 95k miles. it still runs except the problems above. i just changed the ovp relay with no noted difference. i was going to change the spark plug and ignition wires this past weekend but now i am thinking about changing the ignition coils too so i can do it all at once. but the question is, do i really need to change the ignition coils? it's $82 at fastlane and i needed two of them.
