ls swap intake manifold issues
alright so i decided to go ahead and change my manifold on my b18a1 block to a b18b1 manifold b/c a friend of mine said he had one available and Ive been told it was interchangable..so my friend of mine came over and went ahead and put it on for me..well we had the old one off and the new one on in no time...went to start it up and idling very high and surging...come to find out one problem was that i still had my sohc throttle cable so i know that could be one of my problems..another problem i had is coolant was leaking from some random spot and my boy blocked off the lines goin to the breather box.I also have a some sensor on drivers side of the maniold towards the the back end that is not connected either...i pretty much have a mess on my hands that my buddy pretty much up and left me hanging to dry to figure out on my own...Def need this car up and running...If anybody has any input besides NEVER LET FRIENDS WORK OTHER FRIENDS CARS type shit that would be helpful. IF pictures are needed I will definately take some..

take a picture...cause it might be the same problem that i had......for me the high surge would be the cause of the tps sensor and...check your iacv hoses make sure theyre properly clamped cause mine was leaking cause the thing that was holding it down wasnt on the solid part but the rubber .....well take a pic so well know much more whats going on

Need to def find out where the coolant is coming from. Make sure all vacuum and coolant lines are correct. Check the iacv and try adjusting the idle screw on the throttle body.

Re: ls swap intake manifold issues
ok heres wat you do...
1.. take your intake and look inside your throttle body thres should be a hole on the wall...lol not the big hole...... ]back to the topic.. block it with your finger but use a towel cause it will burn you... see if the idle stays down and the same cause it should...if not the adjust the fast idle valve....but the leaking is coming from the block on a nipple right aboove the breaether box that should be connected to the iac valve to one of those if theres none connected already but just to make sure is this wat yout talkin about
