You will have to remove the intake manifold to gain access to the knock sensors. There are two sensors in the valley under rubber plugs. The sensor in the rear has a tendency to fill up with water and cause trouble. You have to make a dam with RTV to stop the water from getting in there.

2003 gmc yukon denali through a mass air flow sensor code changed still having problems with it stuttering to start and while driving on freeway or at stop light when taking off


Trouble codes? If none, then check O2 sensor outputs and replace as needed. Could be a leaking intake manifold gasket if you get "lean banks" codes. This happens in cold winters, but fixes itself in Spring.

2001 GMC Yukon XL idles rough and lacks power code out P0171


P0171 is a lean Oxygen Sensor code. It is trying to tell you that your engine is running lean...not getting enough fuel, or getting too much air. That will cause the poor running and dying. This is most likely caused by a bad vacuum leak. The O2 heater code is probably caused by a failed O2 sensor heater. Sometimes it is caused by an open or short in the O2 sensor circuits, but most of the time it is the sensor itself.

My 2003 GMC Sierra idles rough and cut off sometimes when turning.Replaced fuel filter and changed plugs.engine light stays on.Which 02 sensors do i need to replace first? Before converter or after...


Before replacing the O2 sensors, I would check the fuel pressure. You may also try to have someone pull a trouble code from the powertrain control module to verify why the engine light is on. Do not replace any parts until this is done, otherwise your going to be guessing at the root cause, and it will get expensive with part replacement.

Looking for all four o2 sensor positon


You should have an O2 sensor on each side of the exhaust down pipe, (diver's and passenger side) have one just before the catalytic converter and one after the catalytic converter. That's all the four O2 sensors the Yukon has.

No acceleration


You have to replace the oxygen sensors, the engine computer adjusts the fuel/air mixture by reading the sensors...right now your engine is probably running very rich, which wastes a lot of fuel, and can also cause premature oil breakdown. O2 sensors usually require a special wrench to remove, so try a reliable local mechanic...
