Mobileortho, I was refering to the mass air flow sensor, goes between the throttle body and the air cleaner. Your irratic idle could also be the idle air control. It's located under the throttle body, they get carboned up and need to be cleaned.
Do you have the serial port ( obd 1 plug under dash ) so that it can be scanned?
The master cylinder needs to match the front brake application. For example, my front disc' are camaro so is my MC. Check for a pinched brake line going to the front, like to tight of a bend or kink.
Just thinking out loud, hope this helps.
