2003 Chevrolet Silverado 1500 5.3L Poor Idle Quality, Surge
This engine idles low and surges to stay alive about
450-600 RPM. Misfire counters are counting up on all
cylinders while at idle. After a while it will throw a
P0300 random misfire code. Above idle, the engine runs
great with no cutouts or misses.
