97 Jetta GL 2.0 is having issues starting and running.?

Jetta wouldn't start easily and was sputtering after finally starting. Did a full tune up (cap, rotor, air filter, plugs and wires) and was still having issues. Wiped the codes and read the ones the reappeared and got 302 (misfire on Cyl 2), 341 (Camshaft Position Sensor), and 1238 (Cyl 2 Injector Circuit Open). Info that I have found on 341 says usually that code pops up when the timing belt is changed and the distributor was put back in a tooth off but we didnt replace the belt, which makes me wonder if it finally slipped. But I dunno what 1238 is trying to tell me and I ume 302 is coming up because of 1238. Someone mentioned ECM but I ume 1237, 1238, 1239, and 1240 would come up (each being a cylinder) if the ECM was bad. Any suggestions? The Camshaft Position Sensor is built into the Distributor Ignition on this car by the way, so in order to change it I would have to order the distributor and its $175+. Someone else said on their 99 Golf they fixed their 1238 code by replacing Fuse 32 (10A) in their panel, but I havent checked them all and do not have the cover of course.... Also someone had success by cleaning the M Air Flow Sensor and Throttle Body while replacing the ECT sensor. I did not replace the coil on this tune up either. Please help!
