    Just Traded in my Envoy

    After nearly five years of ownership and 100k miles, I traded in my Envoy yesterday. Really enjoyed the vehicle and interacting with the forum members over the years so this is a bit of a bittersweet goodbye. Thanks for all your tips and comments on my rig. Since I won't be visiting here much...

    Have Fun But Be Safe

    Earlier this evening I heard a very loud crash right outside my home. When I went outside on my balcony I saw what appeared to be a new model Mustang compressed in an accordian type fashion. I watched as others pulled a lifeless body out of the vehicle. A short time later firemen used the...

    Too Bad they Killed the LL8

    The 2014 4.3 liter EcoTec V6 in the new Silvy/Sierra makes 285 hp @ 5300 rpms and 305 lbs torque @ 3900 rpms. While not bad, the eight years older 2006 4.2 liter LL8 I6 makes 291 hp @ 6000 rpms and 277 lbs torque @ 4800 rpms. Just imagine what an updated 2014 4.2 liter LL8 I6 with direct...

    Piston Slap, Rod Bearing Knock or something else horrible

    Just today my engine developed a horrible knokcing/slapping type sound. My mechanic fears the worst. Swapping out my tuned pcm as soon as pcm4less can get me a stock loaner and crossing fingers whatever it is is covered by powertrain warranty. Ugh.

    For all of you not located in CA. you may not be aware that due to refinery fires, "summer blend' gas and other factors gas prices have skyrocketed. Were talking $4.80 a gallon averages.

    Easy method for de-polishing wheels?

    I'm not a fan of chrome or hi-polish for that matter. While I am a bit partial to black wheels, they sometimes appear cheap looking to me, especially when they blend in with the same color as the tires. In any event, is there a relatively simple method to "de-polish" my stock hi-polished...

    Tire Squeal

    For sometime now, I have had excessive tire squel when taking turns, even at relatively low speeds. What is the common culprit? Ball joints or a more simple alignment issue?
