2003 nissan se-r spec v POWER LOSS

The rough idle is associated with the p011 code. The P011 code is: Camshaft A over advanced. There is a mechanical fault with the intake camshaft.
You need to take the car into a mechanic, preferably the dealer since they have all of the needed special tools, to properly diagnose and repair the issue.

Note - not a solution..just adding my woes!
I drive a 2003 Nissan Sentra SE-R Spec V.
My car suddenly stalled 1 day and the engine wouldn\'t turn over. Brought it to my mechanic and had the Camshaft position sensor replaced by my mechanic. The car ran fine for about 2 weeks and then the light was back on with the initial symptoms.

Took the car into the dealership and they diagnosed it again as P0335. Said that the mechanic hadn\'t installed the sensor correctly. Charged me a bunch of money to replace the thing and not too long ago the check engine light is on. The Revs bounce around everywhere. Checked the code again and it\'s P0335 yet again! Am in talks with the dealership to get to the bottom of this...

theres always one on the intake manifold working its way down to catalytic convertor is the oxygen sensor 1 heater circuit(pre cat conv) signal while terminal #25 is oxygen sensor 2 heater circuit (post cat conv)

hi try junk yards,ebay,

Nissan QR 2.5 engine produces a torque of 180 ft·lbf (244 N·m) of torque at 4000 rpm .

Check your fuel pump pressure and filter.

You have to remove the rear seat cushion and there is an inspection hole cover over the sending unit and fuel pump. The 2 come out as one unit. Remove the fuel line coupling and then the 6 screws holding the inspection cover on. BE CAREFUL not to bend the level sending arm. If you remove the fuel filter, make sure you mark which way it came of so it cam be put back in the same way.

Most times when you have a cut in power when the RPM's are high that's most likely a "SPARK" problem. However it can also be a "GAS " problem. Does check engine light come ON if it is or even if it NOT ON there can still be a Code stores in your computer. My first thing would be a BAD CRANK sensor/CAM sensor. This is my recommendations you should have this vehicle place on a code scanner/computer AUTO-ZONE does this check for free then get the codes if any is present and get back to me asap. I strongly thing it would be a crank sensor but if not there is a 20% chance its a FUEL PUMP can meet the demand when you hit the gas therefore then engine starves and dies. LEt me know how you made out. Good Luck and Thanks for using FIX YA

I have the same car and I know there was a TSB for the ECM . I know the ECM issue has cause some cars to stall while driving
