Lads i need your help again, i have recently pulled the motor apart on my ser 2 calais n put everything back together weth some little goodies there is one vaccuum pipe coming off the back of the throttle body that has got me puzzled on were it hooks up to again. its the larger pipe, comin off the back ,right next to the manifold adaptor. if any one could be bothered havin a look..would help me heaps... cheers
Big vac hose off the back of the throttle body should run to the MAP sensor. Follow the air intake pipe from the air box to the firewall and there's a little black box bolted to the firewall where the pipe bends. That's the MAP sensor.
