Dirty Red almost left me stranded this past Saturday. Didn't want to start and at first I thought the fuel pump was gone but it was miss firing so I thought of the coils. Let it set awhile and later it fired right up. I had called a wrecker to tow it to the dealership but luckily did not need it. Well I guess the truck had warned me already when a coil went out about a year ago but I just changed the one and kept on trucking. Now I realized how old they were and changed them all . I had initially changed them at 60k and now here we are at 160k. The last COP at the back of the engine on the driver side was cracked and I guess it was the culprit.
