Asked by AndrewGKing Mar 29, 2016 at 01:46 PM about the 1997 GMC Sierra 1500 C1500 SL Standard Cab Stepside SB

Question type: Maintenance & Repair

Recently put in a new engine in my 97 GMC Sierra
and now its throwing a P0300 code random
misfire. I've changed everything from the spark
plugs, spark plug cables, ignition coil, distributer
cap, distributer wheel, and ensured the timing is
lined up. Just not sure what else to do?
