I want to temporarily hook in a manifold vacuum gauge to see if I can adjust my driving style to produce more mpg. The engine is the 3.5 on a 2005 AWD. Are there any unused taps on the intake I could use or what hose would be good to T into?

Thanks

 

it wont work the software in the computer will simply adj it back to where it needs to be

 

I'm assuming you just want to MONITOR engine vacuum??? Like an Older Muscle car with a Dash mounted VAC GAUGE??? Or a Mid 70s Newyorker or Cordoba with the "Fuel Minder" system in the Left side Fender mounted turn signal pod??

Monitoring is possible, Making Changes , other than the weight of your left foot, is not.

Although....I wouldnt recommend this. There are no "Obviously" un-used ports, and the ones that are there are for "Critical" function. For example..."Tapping" a MAP hose would be a mistake. I wouldnt want to open up a Booster Hose, simply for the safety aspect, and the only other viable point I can think of at the moment would be The cruise Servo, which may cause other problems .

 

Yes it would be to monitor the vacuum.

 

buy a scan gauge it plugs into the OBD port and it will give u instant MPG and the vac u also wanted plus many more sensors readings.
