P0100 A code P0100 may mean that one or more of the following has happened: The MAF may be disconnected, or a wiring connection may be bad The MAF sensor may be faulty If the MAF sensor element is dirty use disc brake cleaner. Do not use Throttle body cleaner because it will leave a residue that will muck up the sensor. A residue on the hot wire element ...

Vacuum leaks can cause a bad MAF reading a result in a fault code. I would check The intake boot connected to the MAF sensor for any cracks or holes. I had this code show up on my '94 BMW. I spent the money on a new meter only to find out that I could have fixed the problem with a $20 intake boot.

The first thing that I would check for is a vacuum leak. Vacuum hoses rot over time making this is a common cause of engine speed problems at idle. Carefully examine all of the boots and hoses connected to your intake manifold.

It's unlikely that 2WD will save you a lot more fuel than AWD but it will save you more than zero. 2WD will definitely save you fuel over the 4WD Lock setting. The reality is that, no matter what setting you use, the engine still has to move the same mass of metal down the road. I.e., maximum efficiency is bounded. That said, in 2WD mode, you are avoiding ...

Most common cause is the ECM Coolant temp sensor may be bad or out of range, replace it. If you have a scanner that can display live data this would help diagnose this as you can see the coolant temp the ecm is receiving from the sensor. Read the temp live data when it has starting issues. The temp when cold should be very close to outside air temperature.

I suspect the only two places you'll be able to get one of those is either the Nissan Main Dealer or a local breakers yard. I'd suggest giving your local main dealer a call as you may be surprised by the price. I personally always try the main dealer first and quite frequently find their prices are competitive.

Milan, I recommend that you purchase a paper Chilton's or Haynes repair manual for your car. They cost around $30 at your local autoparts store. Many manufacturers have provided a 'secret' code that you can use to turn your check engine light into a blinking code reader. The instructions for that tend to be written in the repair manual (not all ...

Regarding the whooshing sound when you remove the gas cap. This could be a defective gas cap check valve. The check valve performs 2 functions. When the fuel pump takes fuel from the tank the fuel volume decreases creating a partial vacuum inside the tank causing the fuel pump to work harder. The check valve injects outside air in to equalize the pressure ...

Hmm. Either temp sender calibration is off a little bit or it's colder inside the car than it is outside the car. Remember when you are in Defrost or Defog modes on your Heating Ventilation Air Conditioning (HVAC) the Air Conditioning is turned on automatically to help remove water vapor from the air, and keep the Windows clear. This will cool the car's ...

You've got a broken or dislodged linkage in the lock mechanism. If you remove the door card (the interior door trim), you should be able to get at it, and reconnect or replace it.

Check the tension on the serpentine belts at the front of the engine - sounds like they're a tad loose. It may be something else, but start there.

The fact that you stalled the car uphill and that it is acting that have most likely nothing in common. Gear knob vibration is quite normal on older cars. Also, when car is on low RPM under load, vibrations tend to be more prominent in manual transmission cars. Start with driving the car on the flat surface to see if it's accelerating as expected. If the ...
