AAA: Government Mandated 15% Ethanol Blend Damages Engines

[soundguy]

ay idea if e15 could be causing dirty throttle body assemblies.

I never rememebring having to clean TB's as much as I do now ? or probably unrelated?

Because it is hygroscopic, ethanol 'pulls' in whatever the moisture has in it.
Water attracts dust, dirt and micro-organisms, ethanol attracts water, and presto!, crap gas.
This isn't a problem for newer systems which are sealed or pressurized, but older systems and gravity fed systems will suffer.
As I stated, ethanol was NEVER a good idea, and it's benefits are in fact, unproven in a purely scientific view.
The reason we have cleaner air is because of higher effiency vehicles and other fuel additives as well as catalytic converters and so on.
Ethanol's part of the equation is bogus, and poppycock.

Marlin 795,

Pity you didn't note what brand//model pickup. Lots of reason for the symptoms you describe ! If your's is a Ford and has the mid-size V-6, suspect the intake manifold coolant runner. OTOH crappy fuel can attack your engine internally via detonation causing head gasket leaks. This could/will result in coolant in your oil. And expensive repairs. >MW

If you're getting fuel in your TB, you've got bigger problems!

unless you have a 7th/9th injector...

not fuel.. but combustion byproducts perhaps?
