P0300 Random misfire

P0301 Misfire number 1 cylinder

P0302 Misfire number 2 cylinder

Misfire are mostly caused by ignition system dealing with the ignition coils, If this is a 4 cylinder engine then there is assortment of reason that will cause the misfire.Buick put out a Recall for poor drivabilty and rough idle where the ECM will need to be reprogramed. and reprogram for stall at a stop. If you have a 6 cylinder engine this is mostly will be with one of the ignition coil. One faulty ignition coil is enough to create a random misfire , Clear the code let the vehicle idle for at least a minute, Turn engine off, Restart check the code, what ever cylinder misfires replace that igntion coil.
