Engine Performance problem
2002 Chevy Avalanche V8 Four Wheel Drive Automatic
Hi, my truck is getting poor gas mileage. On a full tank of gas would only get me around 600km's. Before i was getting over 1000km's. Ive changed spark plugs, air filter, fuel filter, eng temp sensor an still nothing. i was traveling down the highway gas gauge dropping and i floored the truck to pass a car and after that i seemed that it wasnt burning as much gas. So usually when i go for a ride i try and floor it and it seems to help. I am thinking its got to be electrical? The fuel pump makes noises once an a while.
