Hi, I'm new to the website. I have a Chevy Silverado Classic 07 4.3 and it has 48,xxx Miles on it. I recently when i was driving i got message on my DIC (tighten gas cap) i stopped and tighten it. later the next day i had the engine light come on (it annoys me to have that engine light
Well i took it to auto zone and got the code read and got p0455( she said gas cap) so i bought a new one ( put it on ) and then reset the code. Then later the next day i had the engine light come again. I went it took it back and got to rescan and got 3 codes p0442,p0449 & p0455 (im like wahhhah!!
) i dont know what else to do...any had any problems with this?
