me again, vacum question

[javier302]

anyone know where can i get a vacum diagram, as i said before my project car wasn't idleing too good, and we found that cyl. 3 and 4 wire were backwards, it's running a bit better, so i took the upper intake off to check if any injectors were disconected from last week when i clean the tb and the intake, there is 2 hoses in the front and 3 in the back of the pellum, since the car idles a little higher, i'm afraid that i might of made a mistake, and since haynes manual don't show it, what's better than :SNSign:

thanks guys

I was just looking at that site and something occurred to me...isn't there a difference in vacum from the MAF & SD setups? That diagram says its for an 88..which would be SD. What was the difference?

Speed density has one vacuum line that connects to the MAP sensor. It isn't connected on the Mass Air cars, because the MAP sensor becomes a Baro sensor. The Baro sensor vents to the open atmosphere. The spare vacuum line gets capped off.
