OK,I put a 1998 2.5 motor into a 1996 body that had a 2.5 in it, same body style, leg wagon kicked a CEL Map sensor with the original 1996 sensor, also with the one from the 1997 car, the 1997 car had no CEL, the motor was swapped into the '97 car with no CEL I'm puzzled, BTW, same sensor in both cars PLEASE HELP !!!!

Vacuum lines aren't hooked up right. If the hood is original make sure your lines match up to the emissions sticker on the hood.

I read a clogged EGR would kick it off also? is that true?

Not likely. You'll get EGR codes but not a MAP code unless there's a broken vacuum line to the EGR.

The MAP and EGR vacuum hoses should not be connected since the parts are on opposite sides of the engine.

99% of the time MAP codes after an engine swap are due to incorrect routing or disconnected vacuum hoses that go to the MAP sensor. Focus on those first.

survey says...... it was the solenoid, thnx again everyone
