Any GM exclusive mechanics? 6.5 Diesel ?
Yes, I'm still driving my old 96 Silverado with 6.5 Diesel. Mechanically it's very sound and reliable. Several years ago I replaced the PMD (Fuel Solenoid Driver)with an after market unit that was ...

Put the new gas pedal assembly in my truck a couple weeks ago. Also cleaned the air filter (K&N) and did a lube job at home. Truck ran great, commuted to work with it no issues.
Last week pulled our trailer (10,300lbs) to the coast again, not a single issue. Ran fine, cruise control works, felt like when it was new.
On the way home, 6 miles from the state park as I'm coasting up to a four way intersection "service throttle light" comes on and truck will only idle, zero input from the gas pedal. Turn the key off and restart, all is fine, truck runs good. 90 miles to get home, I'm a little nervous. I notice now that the truck won't downshift (4spd Auto) on any hills no matter how far I push the gas pedal down. I have to manually drop it to 3rd on grades to keep speed up. (Remember this old truck is only rated 190 horse power)
Service throttle light comes on one more time as I start up a big grade 5 miles from home, I pop it into neutral, shut it off and restart all while I'm rolling on the freeway up hill. Drop it in 2nd from neutral and climb the steep grade with the engine pinned at 3000rpm, it's pulling hard and it gets us home.
So I'm back to where I was before, just my wallet is lighter by a few hundred dollars for a new gas pedal. Dang I love this old Chevy, but it's no fun when it de-powers it self. I'm out of ideas. Hans
