Help me diagnose this lol...
Ok last time I drove the car it ran fine(about a mth. ago). Been busy w/ the new house so I havent driven it but ive randomly been starting it...well it sat awhile since the blizzard and I jumped it today..Idle seemed like it was racing a little then when I threw it in drive it was kinda lurching forward...so I went and took it for a spin and noticed that the car was slowly accelerating while my foot wasn't on the gas lol...idles definitely off...by the way its the LS1 in sig. Anyone
