i lost the instructions and just want to make sure its rightso i don't have to pull the upper back off. i know there are four ports on the upper intake. the front left (facing the car) port was running to smog so i plugged that one. i'm pretty sure that the front right port ran to the T fitting in the back of the upper intake. i'm not sure about the other side of the T fitting. i think it runs to the vaccuum connecter, teh same one the brake booster line runs too. the firewall side has one big port and a small one that was plugged so i plugged that one. i'm pretty sure the big vaccuum ran to the pcv and the smaller lines ran to the EGR. i should have taken more pics but i didn't. i'll post a pic, but the intake will be upside down. sorry its blurry. thanks in advance.

as long as you've got them hooked up to the intake somehow, it shouldnt really matter all that much

i still can't remember where the small vacuum lines run. i think one ran across the back to the vacuum plug at the passenger firewall side. i really am not familiar with the vaccuum system so i don't want to screw it up. all i need is a vaccuum leak[:@]

One small one goes to the vacuum pod thingys on the passenger firewall, one goes to the fuel pressure regulator,big ones go to the pcv and the vacuum tree on the firewall, front one goes to the charcoal gas tank vent on the front frame rail on the passenger side.

sorry to steal the thread but for the vacuum line that connects to that pod thing on the firewall does it matter which one of those little fittings on the pod it connects to?

If you are talking about the vacuum tree next to the brake booster, there 5 different ports, starting from the right (driver side) the big one goes to the brake booster, next one goesin the driver side finder(cruise control), next smaller one goes to the vacuum pod thingys on the passenger side firewall in the corner, next smallest one is blocked off, and the last one on the far left goes to the intake.

c'mon dont thread jack..... but i'll help out anyway, if it's still a SD car, SD doesnt enjoy hoving the injectors changed or intakes.... you can only add so much hp before they begin to surge [:'(]. the only way to cure that is a tune where they will mess with your a/f tables. also are you sure you stabbed the dist. correctly? it could be off by even one tooth and that would mess things up and make it run like crap
