Ford Repair: Ford Windstar error code, ford windstar, gross leak

Question
After hooking up to the computer, I found 2 error codes.  One, P1538, Intake manifold runner control open Bank 2 and the other P0455 Evaporative emission.  I know the second is due to a crack of some sort in the fuel intake area but what is the first one and what could this cost to fix?  A second question deals with the brake system after driving the car a while the ABS light and trac control light comes on or blinks...what needs to be looked at in this area?

Thanks

Matt

Answer
You did not indicate what year Windstar, so I can't be real specific. Some years had vacuum operated IMRC, some had electric. Usually the butterflys stick or one of the vacuum/electric motors fails, occasionally a rod will come off the motor or linkage. P0455 is a gross leak, even a lose gas cap will set that one.

If the ABS light comes on you need to check codes in that system before you will know the cause.

I don't do prices or estimates, sorry
