1999 Mazda Protege is possessed
 

Hello, my Protege (1999) is acting so strange. The other day when I was at a red light my RPM started fluctuating (moving back and forth between the 0 and 1) like crazy and as this was happening my brake pedal was doing the same thing. It was moving up and down at the same time.

Has anyone had this issue before?

Also, my MAP Barometric sensor is going bad and I want to know if this could possibly be related.

Thank you in advance

God Bless!
