Very commom problem with this car...but it is not the fuel....likey ignition coils failing or a wire harness problem. Nissan had TSBs published about this problem. Check on line for bulletins #NTB01-059 & NTB01-076B.
No way that I or anyone can say for sure what is wrong without having car and testing potentialy lots of different things. But one thing makes me think that since it was running ok before someone replaced crankshaft sensor, that it may relate to that. I see information that indicates there has been issues with the crankshaft reluctor wheel. It does not come with the sensor but the sensor works with that part. Also if timing belt was installed one tooth off it could cause this issue also. Better go back to the begining and start over.
Depends on what engine option you have the 3.4liter engine has 2 different sensors...one is on side of block and the other is other is on the front of the engine behind crankshaft pulley. Both 3.8 liter engines have 1 sensor in front behind crankshaft pulley.
Could be a restricted brake hose...likely the right side brake hose. But I suggest you replace both.
Do you know if the fuel pump is running. Could be the main relay. Main relay powers ECU.
Is this setting a code p0017? Commom problem with the camshaft position exhaust actuator, also known as the phaser. Having problem with oil sludge build up caising actuator to stick. One of the first things to try is draining oil and refill with clean 5w30 or in some cases refilling with transmission fluid to clean passages. engine should not be run above idle to clean and not damage engine bearings. If cleaning does not work...phaser will likey need to be replaced.
The p1149 and p1420 likely relate to one another. p1149 air fuel ratio sensor may be setting up the p1420 catalytic converter failure. At least you hope so...best get a airfuel ratio sensor first and hope the catalyst does not need to be replaced. The P1600 is the most commom problem when the high voltage battery is failing by my research....but a factory scan tool is needed to diagnose that problem.
Perhaps you need a differant scanner to get the transmission fault codes. Not likely that a o2 sensor would put transmission in a limp mode.
Temp control mode door motors are the commom problem. Electronicly controlled system can be diagnosed with compatable scan tool. It likey has fault codes set in system to help determine witch door motor is failing.
Yes I do belive it have 3 cats...2 front ones are part of the exhaust manifolds and one in the exhaust pipe.
