Thanks. I don't know if the code was there before or not. Like I said, I didn't swap the motors. I checked the vacuum lines that I installed carefully and they looked good. Any tricks to testing/looking for small cracks? I guess my next try would be the baro sensor. The are 2 units that the vacuum lines are connected to on the strut tower, one is black (which I think is the baro sensor?) and one is a orange/rust color. Can you tell me which is which?
