Hi, my nissan pulsar n16 is accelerating really slow and it is having problem going uphill. Also when i'm in the freeway my car speed can't even hit 100khp.
what could be the problem?
Thank you for your help.

Hello, I'm Danny,
This situation could be caused by a few different things. First you should check to see if there are fault codes stored in your car's computer if the check engine light is on. Here is a tutorial showing how to retrieve check engine light codes:
Second, It possible you may have a weak or failing fuel pump which might not be supplying proper fuel pressure when accelerating. Here is a tutorial showing how to test the fuel pressure:
I've attached a picture below of your vehicles fuel pressure specification. Lastly, It's also possible you could have a plugged exhaust system or catalytic converter causing this issue. I've attached a few catalytic converter tutorials for you to view as well.
