Well, there goes another camry user who thinks he can get away with servicing with just any oil. You might get away with it for a while but not for too long. A lot of camrys, highlanders and rav4s with this engine are beginning to display the symptom you are having now owing to years of abuse by their owners. if you can still rev ur car beyond 5,000 rpm after it has warmed up, then probably much damage hasn't been done to the cams lobes, sprocket, lifters and valves. Please start using the recommended oil from now on and stay away from anything like oil treatment, ap visco, mobil xhp or any other heavy oil. I have heard a mechanic once recommending oil treatment to someone who complained about something like this. Please don't try it if it has been recommended to you already.

I presently can't Rev my 2AZ-fe engine above 3000-4000RPM. I've replaced new plugs, set of Coils, new fuel pump.

Bad knock sensor
