I can almost confidently say i have the factory coil pack and wires with almost 120k on my truck, (changed plugs at 110). What are some signs that the coil pack and wires need replacing... I've noticed that over the last year my gas mileage has dropped from 15 running about to 13 running about, however i've added a desert bar and upped the tire size from 30s to 31s. as well as the other night i was messing around with my truck in my friends driveway, and i pulled one of the wires out of the pack to see what my truck would sound like with a miss, and the idle didn't change much if at all... so i put that one back and pulled another one, and it did the same thing... then i pulled a third one and it finally started running really rough... do i have a dead cylinder or a messed up coil pack.
