the main thing it turns out to be with no check engine light on is moisture under boot, corrosion

Have you checked your O2 sensors?
My theory is long, because I went through everything summer of 2010, but when I finally got to the O2 sensors I had one arcing out because of a chafed wire

The problem with our trucks is everything is connected, the problem with the engine may not always be located on the engine.

can't hurt anything. All the dielectic grease does is keep out oxygene and moisture.
thanks,
robert

FIXED!!! Call this thread closed!!! Took every injector out, and tested resistance, all good. Took every spark plug out, checked resistance, all good. Took every coil out, checked resistance, all good. The boots were decent, but there was moisture under them. Got new boots and springs, cleaned out every coil chamber and put it all back together with lots of dielectric. All is well. Thanks for all the help everyone!! Hope this helps someone else in the future.
