Answer
Sorry for the delay my dad had a bypass surgery on Tuesday and I am just getting to these messages now.

Map sensor is at the back of the motor in front of the ignition coil.  It has a three wire plug that is green and the vacuum line goes to the intake.  If it isa actually equipped with a MAFF sensor it is in the air intake.  I have only seen two in my life with the speed density update.
