On a recent trip, I was in tow-haul mode and stepped on the petal pretty hard to get around a slow moving truck and the engine appeared to die. No check engine light, all gauges were normal - just wouldn't go over 2,000 rpm. I pulled to side of road, checked everything out the best I could. I found that from turning the ignition off, I could reset whatever was limiting the rpm's. All was well, but was more sensitive to this problem during remainder of trip. I figured some sort of a faulty rev limiter.
Chevy dealer informed me that the fuel filter should be replaced every 15,000 miles if towing a lot. I had 41,000 on mine and he said I was lucky not to have come in on the hook. Since this is my first diesel, now I know better ! The filter was starving the fuel flow.
Also, Chevy found that my air filter was not for a diesel engine. A gas engine filter the local oil change company put on will not handle the volume of air being pulled in by the turbo. I was not aware they had put on the wrong filter.
Best to stay with GM parts, spend the extra money and stay off the side of the road !!!
