SOURCE: Ford windstar OBD II code P1537/38, P0171 and P0420

It could all be related.P1537/38 are the intake manifold runner controls are stuck open.They are controlled by vacuum solenoids.The P0171 is bank one of the engine is running lean,usually caused by a vacuum leak, P0420 is catalytic converter efficiency code. The computer monitors the switch rate of the front 02 sensors and compares it to the switch rate of the rear 02 sensors to tell if catalytic converter is doing its job. Now if the front 02 is not switching properly then this will cause this test to fail and set this code.
Look on bottom section of the intake manifold at the back of engine(where tranny bolts up) you should see the vacuum motors there on the intake,these are the control motors for the intake manifold runners.Make sure the vacuum lines are hooked up and lines are not leaking. Also you will see a lever from it to intake make sure they move and are not binding.

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.

SOURCE: I have a 98 ford windstar with check engine light

These are all related:
P1537 and P1538 are BOTH:
Intake Manifold Runner Control Stuck Open
P0171 is Lean Bank #1
P0174 is Lean Bank #2.
On the front of the Intake Manifold there are Plastic Clips. The Clips are currently broken and need to be replaced. Because these are broke the Computer is registering too much Air or not enough Fuel = Lean.
You should be able to purchase these at any auto parts store (call ahead for availablility).
After you replace these, all the Codes should disappear.
Let me know if this helped, or if you have addtional information or questions. Feel free to contact me at FixYa.com!

  1. Remove two bolts retaining vacuum control and bracket to IMRC housing assembly.
  1. Disconnect linkage from the lever/shaft assembly and remove vacuum control .

As for the misfire codes, Check out the upper and lower intake gaskets. Since you have to take the upper intake off for the imrc valves its just a few more bolts to remove the lower intake. The intake gaskets are rubber seals. When the engine is cold the seals shrink and causes a misfire. when the engine warms up the seals expand and the misfire goes away.

P1537 what does it mean for a ford windstar trouble code


P1537 - Intake Manifold Runner Control Stuck Open.

You might want to look at the imcr valve. It is probably sticking from carbon build up? Use top engine cleaner and clean the air plenum.

Once you have done this clear the codes and go for a ride. About 30 miles should do it. If you have anymore codes it will come back up.
