Just put new plugs and wires into my 04 Silverado 6.0L with 75K miles on it and noticed it evened out the idle a lot and quieted the engine down by at least 20-30%.
I was thinking about running by Walmart at lunch and having them do a fuel injector cleaning. I run a bottle or two of Techron or a octane booster through my truck every 6 months or so, but don't do it every 3k as recommended. After calling and asking, Walmart's service is more than just adding a bottle to the tank, they hook up the fuel return to a bottle of cleaner and blow it through the injectors.
Worth the $20 they charge or would I be better off sticking with the techron (which after reading online is little more than methanol)?
