Hey folks, Back on 7/1, I posted I had a tensioner pulley seize and toss the serpentine belt. Well got all that fixed, but some other problems arose. 1. the stereo, it has no true volume acts like it has no amp ( original stereo), it actually worked 2x's since the incident on 7/1, but if you shut the truck off it was back to no amplitude. 2. mileage, it's stuck at 15.1 MPG and I had been getting 17+ on the highway and that was with a Durmaxmiler where I dumped the +70 tune in the trucks computer. Is there a chance I scrambled some stuff when the belt popped of the Alternator? I've unhooked both batteries to try and reset everything, but the radio came back with the stations and current time, so that didn't work. Any thoughts? I've got a trip coming up with it ( she is not an everyday driver.).
