Are there any known easier ways to change the plugs in a 91 SuperCoupe? We installed what looks like thew wrong plugs while doing the head gaskets and now have a pronounced miss only under boost. Under vacuum the car runs smoothly.
Plugs we removed were Autolite AP 2546 which at that time produced no missing under boost. We installed the new plugs- identical ones- while the heads were off due to ease of access.
Info obtained says these should be Autolite AP 2544 which I think is 2 heat ranges lower. We have changed one bank of plug wires to Bosch 8MM and will be changing the other more difficult bank soon.
Any tips on wire routing/precautions would be very helpfull.
Just how do you manage to re and re the plugs and what methods/tools do you use?
