I have a 94 Mx-3 4cyl DOHC B6
When I depress the brakes (no matter if it is to stop the car or just pressing them while in neutral)
the engine surges, also once I'm at idle, after a second or two the rpm drop down to about 400
or less. If I pump the brakes the RPM will actually restore to about 800. I guessing a vaccum leak.
If you could give me some advice about how to find the leak, or have any suggestions about the cause and repair, please help an Mxer out.
