Well, in the old days, you just removed the rotor from the distributor. Or simpler, the wire running into the distributor. But now cars don’t have distributors. Not nearly as easy as it was before the government regulations got out of hand.
On my BMW it’s easy. Just unbolt eight fasteners, unsnap the cable tray, remove the cabin air filter assembly and the tray beneath it. Remove four fasteners and take off the engine cover. Lift the latch on each of six coils and unplug the coil wires. Easy-peasy!
Yes, I’m messing with you.
And the reason I’m remembering this process is they’re really not kidding about the 100K mile spark plugs. At 100,100 miles I got a cylinder misfire code. Had to replace coils and spark plugs last weekend. Good to go now (not for another 100K miles, this is a BMW after all).
I used to do that to my poor sister to keep her from taking the car we shared.
