Re: miss on 99 5.7l no code, what is cam sensor setting?
Definitely have the distributor gear checked if you haven't messed with the distributor or had the intake manifold worked on. The cam sensor reading you are getting must be the cam retard(or camshaft offset) which is the difference the PCM sees between the crankshaft sensor and the camshaft sensor. I noticed this on my truck after having the intake manifold gaskets replaced and when I checked the cam retard on the scanner it was -11 and the misfire always occurred at light throttle cruise when the pcm was trying to get the most spark advance 36 degrees and more. There have been numerous cases of worn distributor gears causing this same thing and the PCM doesn't seem to compensate and lower timing, eventually it may trigger a bank 1 and 2 rich code but a lot of times you will never see the P1345 that indicates a distributor timing problem. The spec is 0 degrees +/- 2 degrees for the cam retard(crankshaft sensor/camshaft sensor offset) and usually you have to get about 15 degrees out for a P1345 to code, but at 8 degrees you are sure to have some problems
