Wiring can be a suspect. I'd trace it and check it thoroughly, include the wiggle test.

Also consider checking the magnet on the cam gear.

Jon.. please put your year and model into the signature portion of your profile. It helps to keep us from having to reference the first post when diagnosing.

Much of the issues you mention would appear to be power related. Have you pulled your battery cables and cleaned them at both ends, also removing the boots at the battery end to check for corrosion under and inside the cables? That is one fo the first suggestions if you haven't already done it. All three cables can cause issues.

I have cleaned all battery cables and also cleaned the groundbus in each door jam. none of the cables were corroded very much. Not sure what else to clean. i've pulled out the new camshaft sensor and inspected it to make sure nothing has been broke or anything on the magnet and it still looks to be in one piece. Someone suggested it could be the crankshaft sensor but the only code that comes up is for the camshaft sensor

Did you look inside the cam sensor hole and make sure the magnet on the timing gear is still there?

With a persistent code 41, this is the first thing you need to do. Use a mirror (1.5" mechanic'* telescoping mirror works nicely for this) and a flashlight after you pull the sensor out of the hole. Shine the light on the mirror and adjust the mirror so that it reflects the light through the hole onto the cam gear. You will be able to clearly observe the cam gear reflection as you slowly rotate the engine by hand to see if your interrupter magnet is gone. Chances are good it is missing or damaged.
