1998 C 280 - How to change spark plugs
I have a 1998 C 280 that is giving me misfire codes. I got these codes on 2 different cylinders. Once on Cyl # 1 and once on Cyl # 6 . Car has 120k and i purchased with 96k about 3 years ago. I've never replaced spark plugs in this car. I noticed coil has two wires per cylinder. Does it have double ignition? How do the wires remove? Do they just pull off? Don't want to mess anything up. Can anyone advise on how to replace spark plugs?
