My 2005 Nissan Altima has been idling rough for 5 months or so and then started missing while driving last month. Now it occasionally stalls while standing idle in drive or in park and sometimes difficult to restart. Suggestions? Injector cleaner seemed to help initially but now getting worse.

Probably sensors! I have already replaced the crankshaft positioning sensor once, nissan replaced it once under recall and now it is bad again! Plus my speed sensor is bad too! Go to any part store and get diagnostic test ran, it will tell what sensors are bad.

Have you checked your MAF? Sentra's are famous for them having problems, I havent had an issue with mine yet thank god.
