Re: '05 5.3l mysterious misfire

The guy that did my mail order tune told me tech2 was a waste for me(I'm guessing his tune turns the misfire detection off). He told me to get it dyno tuned and the tuner would be able to find any problems. Being as I don't have an extra $600 and the closest shop that dyno tunes is 3hrs away that's not an option right now. I swapped the coil packs with a spare set I had from another engine and the misfire is still there so my next step is going to be to get an infrared thermometer and read the header tubes and hopefully find a difference.
