I have a 2003 with 27811 miles and last night after punching it over a hill, I noticed the truck vibrating a little. When I got home it was real bad. Well I started it up the next morning and all was fine until about 20 miles. Then it started acting up again and then I lost power. I put the petal down to see nothing happening and then dying along the road. If I let it sit for 10 mintues and start it up, I can move again, but slowly in 2nd and then to a higher gear. When I approached a hill, it just wouldn't want to move. I got the codes P0276 and P0272. The local dealer said it is probably bad injectors. I have the extended warranty and hope all is covered int he warranty. I was running a diablo predator just 2 days before and decided to run the stock for a few days to see if there was any MPG difference. Besides not haveing as much power, the MPG were the same. The dealership said it will be a few days to look at it. The tow truck driver told me that if I put 1 qt of automatic transmission fluid in a tank of fuel, it will lubricate the system really well. Any takes on this?
