Default spark plugs

How long will a TR6 plug last? Have 7000 miles on mine and picked up a miss, shows no codes. Trying to figure out if it is plugs or coil pack. Going to change plugs today to see if that is problem if not try coil packs. Motor has good oil pressure no noise just a miss.

what is your gap? I gapped to .060 on my TR55's and they missed on my 5.3l truck motor. Re-gapped to .045 and the issue was resolved

Ignition missfires can be any # of problems including parts of the engine that are not ignition at all , in other words a miss can happen from lower compression in a cylinder and thats the only problem or multiple prob causing miss .
