2007 Silverado 5.3 V8 with AFM with 180,000 miles Truck had lifter ticking sound and white smoke upon every start up which would go away after a few minutes, no check engine light Replacement list : - headgasket - valve gaskets - upgraded drivers side valve cover - valve stem seals - intake manifold gasket - exhaust manifold gasket - 8 new afm lifters - 8 new non-afm lifters - head gasket bolts - engine coolant temperature sensor - spark plugs - spark plug wires - fuel injectors - water pump - thermostat - cam sensor - crank sensor After completion of engine reassembly no longer had white smoke upon start up and no ticking sound but flashing check engine light code p0300. Code p0300 was for cylinder #1, #4, & #7 Moved coil packs between cylinder #1 and #2 to see if coil packs was bad but no change. Set engine at TDC before installing the rocker arms. All bolts have been properly torque and no parts have been left unplugged or uninstall. Any possible advice would be helpful

S10 Sputtering at Idle and Check Engine Light Flashing
djpardi posted a question in Ask the GM Technician
I found this thread on this site that seems the closest to my issue but I wanted to get a few other comments before I start: http://www.gm-trucks.com/forums/index.php?showtopic=62425\ I have an Chevy S10 4x4 '02 6 cylinder crew and I have a very similar issue (as seen in above thread). Last I started the S10 there were no issues. This morning I started it and at idle it is sputtering and hesitant when gas is applied. The check engine light is flashing. I shut the truck off to see if it would solve the problem and the engine turned but did not start up right away. I waited about 2 minutes and it started again but still sputtering. I had to get to work (~6 miles highway driving) and noticed there were no issues at high speeds (~55 mph). The sputtering resumed when i was off the highway. I read one forum saying the pistons could be running into the valves causing the sputtering and I am very worried that the engine may get damaged beyond repair if i drive home if it hasn't already. I also read it could be any of the following problems: -Fuel sensor -Vacuum leak -ignition or fuel injector -oxygen sensor -and now the Vent screens Can you give me any suggestions. I know the first thing I have to do is get the codes from a local garage I'm just a little afraid to drive the vehicle in its current condition One last note that may or may not be of relavance. Over the weekend Snow Storm I noticed a large accumulation of snow under the entire truck when i backed it out of its parking spot. The truck was not sputtering at this point it i noticed it the next day
