Tip & How-To about Nissan Altima
If your 2005 Nissan Altima is sputtering or seems to stall in mid drive at speeds of 55-70 mph or just shuts down at low speeds or idle this may be due to your crank shaft sensor.
The crank shaft sensors were originally made of plastic and were later "upgraded" to a metal sensor.
To change you will need a 10 mm Hex socket wrench, a long flat head screw driver, and if you have access I would recommend a lift.
To access the sensor you will be under the vehicle and you will see a guard plate over the exhaust, remove this so you can have some arm room to reach up behind the engine. reaching up with your right arm you should begin "blindly" feeling for the sensor which by looking at the new one you can be able to tell what it feels like. There will be the connector you need to detatch be careful not to break it. Once you locate it use the wrench to remove the bolts and the flat head to help wedge it out. Once the sensor is out you
Once you remove the old sensor the new one will be a tight fit but it does fit, be sure to attach the sensor cords before putting the new sensor back in. but once you have it attached take a little oil and lubricate the sensor to help it slide back in, reattach the bolts and now your done.

Here are the common cause of surges, stalls at stops, slow idle speed, erratic idle, it is in most cases the idle speed control air-bypass valve and/or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving
