Cap em. Make sure youve got a hose ran to your FPR and one to your firewall map sensor (its correct to use hte firewall map if you still have a obd0 ecu)

[Jermz478]

gotta question.... where do i run the mapsensor vaccum from off the firewall to?? anywhere on the intake manifold?? theres no where to plug it on the gsr throttle body

[green91]

run it to either of those ports on the intake manifold

NO ^^^^^ .... take your firewall map sensor off an use the one on the top of the TB !!!!! ...the red circle at the bottom of the picture is for a FPR ... the one in the rear next to the IACV .. cap that one only .

They are all constant vacuum sources, it doesnt make any difference. In fact, on some throttle bodies not all ports are vacuum, they are pre-butterfly valve.

[turbob20]

use the one on the throttle body. and ditch the firewall one. both read the same.

They do not read the same. you guys shouldnt spread false information
