2008 grand prix cut off while driving. Hesitated to start back up but it did. Now it runs very rough and there was a burning smell coming from under the hood. Check engine light came on after all of this happened not before. What could be the problem? 1 person has mentioned that 1 of the spark plugs may be burnt out...

try jumping again and feel the postive cable the red one to see if it gets hot if it dose its probably the starter ..the burning smell could be the cable getting hot.

SOURCE: Engine running really rough...whine sound when it isn't.

The run rough problem is due a cyl.mis firing,it becaused buy a bad plug,plug wire,coil,or even the ing.module. the servive eng.light flashing is warning you that you have a cyl.misfire that can cause damaget to your catltic converter if you continue to drive it.with may lead to why you think you have a exhaust problem,it may be colgged.

It was the Cat. Converter on mine, Don't drive it like that too long as it will send exhaust back through the EGR Valve and burn a hole in the Intake Plenum....

sounds like you have a vacuum leak, check all the vacuum hoses and replace any broken or kinked ones, also check around the intake manifold gasket for leaks. any air leaks after the air flow meter creates 'un-metered' air which inturn will make the car run rough and stall, hope this helps

SOURCE: car all of a sudden started running rough and smell of burning

No i have grand am gt no problems sounds it may have a internal problem
