p2004 (Intake Manifold Runner Control Stuck Open)You need to take a look at the IMRC actuators on the intake manifold. You can try using a screwdriver or other tool to move the actuators to see if one is stuck in the open position. Do not use your fingers to do this, because if one is open and decides to close it has a bit of force behind it and can injure you. If the IMRC is stuck open, it is usually due to deposits in the intake manifold. Repair involves removing the upper intake manifold and cleaning out any deposits in the IMRC plate area. I would try running some Techron Concentrate in 2 tanks of gas to see if it dissolves enough of the gunk on the plates to free up the stuck one. Certainly a lot cheaper than having to pull the intake manifold and cleaning the plates. Always run tier one gasoline like Shell or Chevron to reduce the buidup of deposits.

The po171 code means the system is running too lean.
Try cleaning the maf sensor (mass air flow) and see if that works.
It can be cleaned with intake cleaner or brake parts cleaner that"s in a spray can.
The maf sensor is located between the air filter and the throttle body in a big black hose and has a wire connection to it. Be very careful when you clean it.
