MAT sensor has a vacuum blockoff cap installed on the IM. Im thinking it goes to a tree on the driver side fender, but theres nothing going in or out of it...its gotta be the reason my renix runs pig rich.

the famous website thats helped me and help you to know what im talking about. That sensor *MAT*shown on that site has been capped off.

I also found my exhaust manifold bolts backing out and getting loose, i tightened them up real good, i found it odd they came loose.

So whats your question?

I can take a pic for you, but I need to know what you want first.

Need to know where the vacuum line goes from the MAT sensor (looks like a brake bleeder screw on top of the intake manifold.

The MAT (or IAT) just screws into the intake manifold, its a 19mm head.

Ill go out and take a pic of my manifold though.

Here, left and right sides. You can see the IAT sensor in the second pic, its the big copper thing with the bolt head and two wires.

If you need another pic, just tell me.

You can see my MAT sensor, its been capped off its the bright red vacuum cap in the picture. See the screw? thats also plugging a vacuum line. Need to know where they go. I apologize for the poor quality it was a lot brighter on my I phone


Thats the tree on the fenderwell (driverside) its missing lines as well as the lines on my airbox are both disconnected.

Again i apologize for the poor quality bear with me
