P0011 & P0121 issues
I have changed the cam sensor, and solenoid magnet but still getting code P0011. Right after I changed the sensor, the truck seemed to run better when I did a test run but the next morning it was back to the roughness when in 4 cylinder.
I changed the throttle sensor a few months ago and code went away but ever since the P0011 code started showing up, I’m getting the P0121 code again. My battery voltage has been fluctuating a lot lately as well, sometimes getting as low as 10 volts and then jumping up to 14 volts. Does anyone know what is going on, I can’t find anything online.

I would look into voltage problem first, check out put at alternator,is it fluctuating there?have seen the stud on alternator a problem, not attached properly, causing a low charge, another check,is the connection hot?
