Does Trouble Code 62 have anything to do w/ driveability?

'93 B250, 5.2L

After an incorrect diagnosis that the alternator was bad, and subsequently, that the PCM (which I understand, regulates the alternator) was faulty, BOTH were replaced and now there is a very noticeable miss. Prior to the alternator and PCM replacements, was getting error code "41". Now getting error code "62". Code 41 was cured by repairing a tiny (22ga.?) wire going to the Neg(-) terminal of the alternator.

Since the Check Engine light is NOT on, I'm guessing that code 62 does not have to do w/ driveability...

Could the replacement (remanufactured) PCM cause the miss? Would code 62 have any play in this???

Thanks for input

 

Depends, what's a code 62? Are we all supposed to go look it up for you?
