03 chevy silverado 1500 4.8 p0300 code
Recently my truck has been sitting a lot more than normal and the other day i jumped in it to head to a buddys house when the check engine light came on. P0300 random and multiple misfires. as well as p0455 large evap leak. well ive tried everyhting i can think of and still no luck fixing this problem. Runs righ at idle and as soo as you rev up engine like starts flashing. Any help would be appreciated
