Suddenly Lost 4? cylinders--trac off
2006 M6 GTO with 102,000 miles. Changed plugs and wires 2 weeks ago. Only mod is Volant CAI. Driving on the freeway at 75mph, engine suddenly started running rough the TRAC control went off and button does nothing. No check engine light??? Pulled off freeway, engine is missing badly on multiple cylinders on both sides. Disconnected/reconnected battery with no improvement. Drove the remaining way home with the average mileage increasing all the way???? Pulled all plugs and wires--nothing wrong there. Started up and checked temp of each exhaust port/manifold. Cylinders 1,3,2 and 4 are cold. Disconnected and reconnected all the basic connectors with no change. Now have check engine light-flashing. Code set is P0300--Random misfire detected. Any suggestions? Is there a good place or person that is good at trouble shooting these issues/cars here in Phoenix??? Replaced the cam sensor this evening--no improvement
