      I have a 92 Cabriolet motor in my Scirocco - had the MAS at an angle in order to get the air intake around the brake booster. no room for original air box.

      When warm the car idles up and down almost like a vacuum leak...mostly based on temperature though, does not always do it.

      Want to remove the MAS - is there a sensor replacement I can use?

      Read one article about disconnecting the computer, disconnect MAS and it would work using the 02 sensor as a fuel/air mixture.


      Looking for ideas. I know Mitsubishi's have a replacement module that goes on the intake manifold.

      Your best bet may be to get a mk2 intake manifold that puts the TB on the passenger side to avoid the issue with the brake booster. You would need to extend the wiring for the MAF sensor, but it's not a good idea to run without it.

      You should also go over everything and make sure you don't have any vacuum leaks and that the ISV is working properly.

      This is what I would do. You'll need a MAF sensor and that could be installed anywhere you want. The converter will send the right signal so the computer is happy.

      On my 92, I had a hunting idle, and noticed that my ISV wasn't Hummming on key on. This lead to a broken wire in the harness about 6 inches up in to the sheath at the right.

      On a 92, the ISV should vibrate at key on, if it isn't then there is issues with the wiring, side note do not unplug or plug in the ISV with the engine on or the Key in, as you can blow your digifant controller.

      I've unplugged my idle valve numerous times while running and never had a problem.

      Unplugging is one thing, plugging in is another...."Just Don't do it."

      Mighty handy doo-dad.
      Many many moneys though.

      Then you probably do not want to know how much a custom frequency valve controller costs.
