ozzinc Posted August 24, 2010 Share Posted August 24, 2010 on my turbocharged 240z i have a map sensor and im using a q45 throttlebody, i think that i may have the vacuum hose on the wrong line coming out of the throttlebody because its hard for me to adjust my fuel and im running real rich with hesitation when i give the car some throttle, what is the best location for that vacuum line coming from the map sensor.

RB26powered74zcar Posted August 24, 2010 Share Posted August 24, 2010 You really need to reference the manifold pressure from the intake plenum. Having it hooked up to your throttle body is insane in my opinion... Quote Link to comment Share on other sites More sharing options...
Challenger Posted August 24, 2010 Share Posted August 24, 2010 The TB port may go behind the butterfly which is the same as in the manifold... might not be your problem. But it might be better to just put it in the middle of the intake somewhere. Quote Link to comment Share on other sites More sharing options...
