1996 Chevy Cavalier 1996 Cavalier P0335, P0341 codes check

My Cavalier is older and high mileage and I don't want to put much money in it so I try to fix it myself. Recently with the hot humid weather it has been running really bad. Suddenly it wants to stall every once in a while and while driving its really jerky and getting progressively worse. The check engine and ETS light have been coming on and going off. I finnaly took it in and got the codes read. It was p0341 for cam position sensor and p0335 crank position sensor. I find it wierd that both of these are coming up as a fault at the same time. Am I crazy to think that its the ignition module thats bad? Today its cooler and drier. I disconnected the battery and reconnected it and the check engine and ets lights are gone. It ran fine and I drove it around for 10 minutes with no issues. I have noticed I have more problems when its hot and humid or raining. Is this an open and shut case for a bad ignition module?
