At any time, day or night, whether engine is cold or warmed to operational temperature, whenever the truck is moving, this noise occurs. Its not always constant, but rather mostly broken into inconsistent intervals of serveral seconds. When I touch the brake pedal (whether or not any actual braking or slowing), the noise abates for several seconds, then continues as described. So my mind leads me to vacuum booster on the power-assist braking assembly, or perhaps the turbo blower. I visually checked, but all appears normal. Odometer reads 155k miles. Serpentine belt appears in good shape. Performance is normal, nothing indicates a problem, except this noise.

The truck starts everyday and runs fine..but it seems like every 10th or 12th start i will get a grinding noise (once or twice) then it will turn over and run fine. Could this problem be the starter? or the teeth?
The start did just get replaced.

I just purchased the truck. The gentlemen informed me he had just replaced the injectors last year, all 8 of them. Then while driving it the other day i noticed a little white smoke when I took off. I asked around, one of my buddies said i could have something in my air intake causing a little white smoke? is that possible or are the injectors going out again?
I figured I would add some better fuel treatment? and get a oil change plus buy a new air filter..

why does my truck read " reduced engine power "
