1997 K1500 with the 5.7 Vortec. about 165k. After this started I changed the spark plugs to no avail. I have a feeling its something worse such as a bent valve or something. It happend when I floored it from a stop to get ahead of someone while I was fully loaded with two dirtbikes, gear, 10 gallons of gas for the bikes plus a full tank in the truck. Only code I pulled was a P0100 (MAF) and P0300 (random misfire). Cleared the codes and now there is no code granted I haven't tried driving it for fear of doing more damage.
