My stupid Vortec is misfiring again. Last time it was cylinder 8, after much digging and trial and error I discovered it was because the stud the rocker was sitting on had come out. So simple fix, put in a new one and redo all the settings. This time it's cylinder one, fortunately easier to get to after you pull everything off just haven't got to that point because it's so damn cold here. I changed out the spark plug and wire and still nothing. Took the distributed cap off and cleaned up the contacts put it all back together and still nothing. I was told to check out the ignition coil, but I thought that was only the case if the engine was missing on different cylinders each time. This is consistently cylinder one. Any ideas? This has me really
