Default Update on p1391 sensor mess

We changed the idle air control sensor after a code was also being thrown for that. That removed the idle air code, and it seemed to run alittle better afterwards, but driving down the road I am still experiencing the same problem. I still have the p1391 code saying imterim loss of crank or cam... Both have been changed, we checked the connections at the ECM and they were fine.

I am really at a loss now. Could it be a bad computer? Or anything else that would still cause it to throw a new code even after replacing both sensors?
