What is the adjusting screw by the pressure sensor for?

Icemark

idle mixture,

And your title of the thread has been edited to actually have the question in it.

Isint called the variable resistor? It has a screw on top and is somewhat shaped like a diamond and is black. I saw it in the FSM.

k and how for do you adjust it properly?

You will have to make a jumper wire for the white plug over on the driver's side of the car next to the headlamp. Then start the car and turn the screw until the idle moves up a little, then turn it back just a little. Be sure to pull out the jumper wire or your car will run baddly. Check the FSM for specifics, that is kind of an over-view. You can get FSM online at http://www.iluvmyrx7.com/

could improperly adjusting this cause your engine to blow?

no.. stock parameters are pretty limited.. you could stall though.

The variable resistor adjusts idle mixture only, and you can't blow an engine at idle.

oh cause I played with it and the rotor went pop!

I thought our motors are suppost to go "pop" at idle.. along with that awful smell.
