Check Engine Light and Service Traction Msg
Please help... I just bought a used G6 GT 3.5 about a week ago with 43,000 miles. It ran good for about a week. Now acceleration is sluggish, hesitatant (jerky), the check engine light flashes and then goes to solid accompanied by the traction control light going on and off (and Service Traction message on the radio display). The problem is worse when I start from a stop (although I have encountered it all speeds). If I press moderately or hard on the gas, the problem appears right away.
Any help would be greatly appreciated.
