Nissan Primera headache
 

Hello to all people!
I'm starting to enjoy my Nissan Primera, but have a kind of trouble, it runs ok without problems, but check engine light
keeps appearing ,sometimes shuts off, the diagnostic guy told me that there are 2 mistakes, fuel-injection time feedback and fuel-
injection feedback 2.
He resets them but they appear again, after 2-3 minutes of driving. Any thoughts on this , someone could have some kind of similar
problems, mechanics are not so sure what can cause the problem, they mention some injection timing valve :eek:
Thank you, best!

sorry its Primera 2001. 2.0 td
