Well about a month ago one of my coils went out, the car was misfiring bad so i replaced it (#3) and then like 2 weeks ago i got a code for coil (#2) to replace.. This one was not as bad but it was going out, car would skip at about 3000 rpm so i replaced it and the car was running good. Now a few days ago the car started to misfire at about 3000 rpms again, car still runs okay but the coil is going out..

so my question is, is it normal for coils to all go at once? or could there be something making them faulty? :/

thanks!!!

 

I think something is making them go bad.
