How do I fix the p2004 control manifold Runner stuck open

SOURCE: ENGINE LIGHT ON SLIGHT LOSS OF POWER AND POSSIBLE RATTLE

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.

SOURCE: I have a '96 Ford Windstar 3.8L & getting OBDII P1537 code.

A common problem on Windstars, there are two IMRC valves, the only way to fix them is replacement, which is not that hard. They are mounted on the end of the intake manifold and control runner length. There is a front and rear one, I'm not sure which one this is but you'll probably have to go to Ford to buy it and they should be able to tell you with the code number. The problem will not affect driveability that much, but if you have emissions testing at your location, this will likely cause it to fail.

what engine? So the guy running the test could'nt point it out to you? You need to find a shop that qualified to repair the car. its a valve on the intake manifold that opens and closes to help th engine produce the most power at low and high rpm. they get stuck. sometimes you can clean them.
