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

 

Ya I think I'll change spark plugs and boots. After I do all those tests.

 

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.

 

never thought of that.... good lookin out

 

well i was out for the night and just got back so no further improvements. ill continue tomorrow. i did notice that one of my rubber boots is different from the rest. maybe they are crap.

 

so I am in process of cleaning everything and there was corrosion between the coil spring and the coil, do i put the dielectric grease on everything? even up in the hole where the spring attaches to the coil?

 

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

 

you all also covered your boots in the grease and then put them down in the hole?

 

Yes this is fine as well, will do the truck good....

 

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.

 

Sweet! now dont be a turd and dissapear untill the next problem you have with your truck. Stick around and pay it forward!

 

YES IT DID...


Having issues with mine. Going to remove EVERYTHING tomorrow. and CLEAN it all. Grease it up. b4 I go spending $$$.
