WE were driving last night,everything normal,then the "service engine soon" light comes on,and it's like I put the car in neutral.engine kept running,no ugly sounds or bad smell,no smoke,just...nothing!Shut it off a few times to see if something would reset,but problem persists.Got it towed home,but not sure where to take it for diagnosis.Anybody else ever have this happen?Any advice would be great! Thanks
