My 2003 Altima V6 has power loss when driving up hills. I have recently replaced spark plugs, air filter, oil, oil filter, cam shaft sensors, cam solenoids and no change. The car will also start to burn oil after about a 1000 mi into an oil change. No codes are on the computer. Otherwise, the car drives fine.
Any ideas?

You could have intake or exhaust blockage. someti mes the catalytic converter wil fail internally and fall in on itself clogging the exhaust and the Altima has like 6 converters. The ones nearest the engine are most likely to fail.
To go over more possiblities I am giving you a diagnostic walk through. Just use the link below to get to it;
