2001 Chevy Silverado V8 Four Wheel Drive Automatic 103000 miles
When I first start the truck it makes some really loud clunking noises and once the engine is running it sounds like a rattling noise. It does not seem to get louder when I revive the engine up. I also have noticed that when on the interstate It seems to lose power when I reach 75 to 80mph and sounds like it is struggling for air or fuel not sure what is going. Thanks for any help.
