I have an 02 lancer cedia and about a month ago it would sputter and feel like it’s dying every once in awhile, until it finally went out and the check engine light came on, a ton of black smoke cane out at the time. I decided to take it to the mechanic (don’t know much about Mitsubishi’s), the mechanic said one of the coil packs was bad. So I decided so I decided to have him change out the coil pack and spark plugs. This whole evolution happened twice because the first time he changed it he only had a used coil pack on hand. Well after the second time, when he installed a new coil pack I took the car home. It ran good for about 20 miles then it started to sputter very faintly every so often, mostly at an idle or take off. I don’t want to keep changing coil packs when it might be a different problem. If anyone has any suggestions I would appreciate it greatly.
