Well my truck has been running like SHIT lately. So i decided to replace the plugs and wires. Plugs went good. Saw that one plug since i switched to bosch about 6 months ago and it still ran like shit. ANyways i saw one hadnt fired at all and then one fired at one time in its life and now it doesnt. So therfore i think for the past couple of weeks i have been running on 2 cylinders!!! So i switched the plugs and onto the wires which were a bitch to change. I had to take off the front passenger side tire and raise up the rock gaurd. Thank god i will be yanking this motor out in 3 months!!:soap:
