Well I stand corrected, I found one big mistake with the vac lines, when I tee'd off one of the lines to make up for the missing one on the 4.3 TBI I hooked the MAP up to the one I split and that one only had vacuum when the throttle was open and MAP needs constant vacuum. It runs a lot better but I havn't had a chance to put any miles on it because I have an exhaust leak which I need to fix first. Has anyone had the exterior oil cooler hoses leak? They have special fittings and new hoses are only available from the dealer and the are like over $150 each?
