Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
do you have access to a good scan tool that can read abs and traction control codes?
generally a coil is the culprit but I always change he plug along with the coil.. These are pretty common for steering angle sensor failures and even wheel bearings.. Fix your misfire and have the abs / traction control system scanned for codes
a easy way to find out if its the coil is swap the # ***** coil with a coil from another cylinder and reset the engine light ..if the miss fire moves to the cylinder you swapped with you know the coil is the cause
what motor 5.3?
the coil is what the plug wire plugs into the 4.8 and 5.3 has a one coil for each cylinder as shown in the attachment
