My nissan altima has rpm issues

Does it run fine otherwise? (Like it's just not reading correctly) or is it actually lacking the power also? Sounds like either the crankshaft position sensor or cam speed sensor

Okay well it starts up fine but i forgot to mention there is a delay when i put it in drive and in reverse, like i will shift it into drive and it doesnt move after a few seconds past the car will jerk forward, and same for when its in reverse

There is a bulletin in regards to the delayed shifting....I took the 2 main pages from it to give you an idea where to look on that part....unfortunately I can only post 1 pic at a time so I'll just have to comment again with the 2nd pic

Hope this helps

If you google 2013 Nissan Altima shift delay you should be able to find the full bulletin from Nissan techinfo.....it will be a disk docs pdf file
