I'd like to measure the vacuum at idle to get a baseline figure for reference. Can anyone suggest a good hose to connect to that's easy to access?

 

Manual doesn't help much, but I'd look for any small hose on the upper intake manifold. Worst case you could drill and tap a port on the manifold, it's plastic so any shavings "probably" won't hurt the motor.

 

Reference for what purpose?

 

Also an Autel AP 200 should be able to read manifold pressure, along with a great many other parameters. I'd buy one before drilling a hole.

 

My Torque app shows the Vacuum from the MAP sensor at 20.67 in/Hg at idle. The manual says the normal range is 15 - 22.

This exercise is purely informational. Just want to get a manual reading to compare against the computer reading, and have the practice of knowing how to measure it if I ever suspect the MAP sensor is faulty.

Now on to Turkey and pie. Happy Thanksgiving!

 

There are many ways to troubleshoot a faulty MAF , one of them is to monitor the fuel trims .

 

Or just save all the hassle and buy a new MAF for $25.

 

MAP sensor, not MAF. The challenge in replacing the MAP is not the cost of the item but the difficulty to perform the task for a component that is hard to access as well as the risk of breaking the connector. In this case, a proper diagnosis is better than the parts shotgun.
