you know instead of capturing the fuel tank evap gases thru the Thtttle bodie evap solenoid., i wonder if i replumb the evap solenoid directly to a bottle of techron fuel treatment would this be just perfect amount of techron to clean the valves and manifold?

lol, sounds good to me. Or maybe meth injection but with straight pea.

 

*edit* could you use a meth throttle body injector as secondary fuel supply?
