P0300 & P0021 Reading Please Help
 

I have a 2005 3.5 se Altima, The car is idling very rough, I took it to advanced auto they did a diagnostic test and came up with codes P0300 (random/multiple cylinder misfire) And code P0021 camshaft position actuator, I have to believe that one of the problems is causing the other?

Any help would be greatly appreciated.

thanks

did they advice you to bought new one for that? How old is your Altima ?

It's a 2005 Altima 3.5 All they did was to do the diagnostic test and give me the results, Just wondering if anyone else has had this problem and if so what was the fix.

thanks
