ok i'm changing my plugs today, and i was wondering if there is any way to check or clean the coil packs? i have some MAF sensor cleaner, would that clean off any contact surfaces? it was just an idea i had, and i figure if i'm already in there i might as well clean what i can. 02 impreza wrx
You should clean the contact (metal portion that hits the plug) of the coil with a brush and nothing more.
