Hey 86, I think if I remember correctly that we are supposed to take the MAP senser and disconnect the vacuum line. I think I remember taking the vacuum line off and leaving the wiring to let it do something that it still needed. The MAP senser is the one on the fire wall right behind the intake, it is the little black square plastic box that is next to the vacuum tree. With the change in system, it changes the purpose of this senser. It may be in those directions I faxed over to you. Is this what you are talking about?
