sensor on 2004 Nissan Pathfinder

2004 Nissan Pathfinder. While on the I5 going 70mph my engine lost its top end power. I equate it to losing 1/2 of a $bbl carb... still going but no get up go harder, faster (ie need to pass?) I have been told possible O2 sensor and Cam sensor(P0304) I've been told that the can sensor is a regular issue with this engine? any ideas and or costs associated?, thanks in advance

it sounds like your check engine light is on. the code for the cam sensor may not be the sensor. it could the vvt system is not working correctly causing issues. do you change your oil at the correct times? if not, the sludge gets into the vvt system and cusing headaches and much repairs required.

We try to change it every 3000 to 5000 miles. If we missed it would be no more than 10,000, and yes your right the service engine light did come on shortly after I felt the change in power. And the wt system is??? Thanks Roy
