2000 Chevy Silverado 1500 5.3L 2wd. Has a rough idle and "Service engine soon" light. AutoZone gave me the following codes: "P0131" and "P0300." I have changed the plugs and wires, what's going on?
Also, there is a squeak that sounds like a belt when I first start the truck and sometimes continues, and sometimes doesn't (may or may not be related).
Also, the heat in the truck is not as hot as it used to be (once again, may or may not be related).
have the same problem?
