I have a 94 4.3 with a stiff throttle. It only sticks at idle. Once off idle it moves freely. When engine is off, it moves freely. I have cleaned and lubed the unit, the cable and pedal pivots. Any help would be greatly appreciated!

- Upgrade to a 2026 AT4 with the 3.0L Duramax

  +1 for the 3.0 Perfect for 1500 pickup towing duties. Perfect engine for a 1500 pickup period. Huge torque at stunningly low RPM makes it feel a lot lighter than it is. The fuel mileage is insane for a tall and heavy 1500... 30+ on the highway. Mid 20's around town. It's probably not perfect if you bought a 6.2 for the braaaaaaapppppp V8 noises and wrapping it out to 6k. The LZ0 acts and sounds like a small turbo diesel and there's nothing you can do to make a small turbo diesel sound like a big one, and you can't make an inline diesel sound like a V8 diesel/big Duramax. It's a different driving experience altogether. Drive one, I think you'll like it, though...

  I'll bet your truck lost the bearings on a roller on 1 of the lifters, and now is wiping out a cam lobe.
- "Reduced Acceleration, Drive with Care" message for Valve Body malfunction

  2024 2500 gasser with 47,000 miles. Driving on interstate Friday when my truck shudders, downshifts, and I get the above message with check engine light. Transmission would not upshift. I had to drive home 2 hours at 65 mph at 3600 RPM with transmission temps 190-200 degrees. Got it to the dealer Monday. They ran the code and said the #1 valve body was malfunctioning in the transmission. Miraculously, they had the part in stock and I had a new valve body installed that day with new transmission fluid/filter. Thankfully, all under warranty. Shout out to Everett Chevrolet in Hickory, NC.

  My truck rarely sees a dusty, dirt road, if ever. Actually, never. Within 6mo of ownership, mine was totally covered with road dust and yellow, Louisiana pine pollen. I swear, it looks 6yrs old. You'd think it was an oilfield, or pipeline service truck. Did GM just do a piss poor job of sealing the bay? Anyone else with this issue?
