Exactly what codes are being thrown? There are multiple codes for those two components. Did you just replace the MAP sensor, or did you test it to verify functionality? After replacing those parts, is the CEL still on?

How long of a delay is there between your 1 long and 3 shorts? You might just be throwing a 13, which would also cause your problems. Do you have a multimeter?
