Hi,
I'm new to Diesels. I have a 2003 Silverado 2500HD DuraMax. Everything in it is stock. It has 153K miles. I recently had 4 of the fuel injectors replaced. The others tested out good. The air filter is almost new (about 3K miles - Fram ToughGuard).
Earlier today I was parked up a steep hill and had less than 1/4 tank of gas. To make a long story short, the truck died on my right after cranking and it took some work to get it started, but after adding fuel it finally cranked.
My question is this: After getting it started back up I drove the truck around and decided to test the acceleration. I noticed that when I'd floor it (at about 20mph) the truck would accelerate until it got to about 2900-3000 RPM and then act like it was choking out: It would sit at that RPM range and start loosing power. As soon as I let off the gas slightly and the RPMs dropped to about 2500 it shifted up and the turbo kicked in. This is the first time I have noticed it do this. I normally don't floor it (gradually accelerate and let teh turbo kick in), but this time I wanted to push it a little more and see what it had. My thinking is that it should have shifted up regardless of the RPMs. I had about 1/2 a tank of fuel when I was testing the acceleration.
Any comments / suggestions would be much appreciated.
