1998 Dodge Ram CAM position sensor

Ok I would suspect that maybe you have injector problems in those two cylinders. Do you have access to noid lights so you can make sure they are getting the pulse signal? P1391 is a cam sensor code what is saying is that the expected signal disagrees with the actual signal. So what we have here is the cam sensor arguing with the crank sensor. So what you need to do is check for good grounds to both sensors and make sure you are getting 5 volts to both sensors with key on engine off. From there without a scanner that has an oscilloscope or an oscilloscope you can not test yourself any further then that. Now also check that there are no pinched wires between the heads and block and intake and any possible brackets that could cause a short that would make the sensors disagree with each other ok. Let me know how this goes and we will go from there.

With everything you are telling me it is pointing to the crank sensor. That is what he code is about it is saying that between the cam and crank sensor that what they should be telling the computer that one is not. There is a long test procedure if you would like to go throught it that is find let me know to get you test tc-40. Thanks
