Airflow Potentiometer removed -- Shud the car run alot worse?

I disconnected my potentiometer today trying to route down my misfire and with it removed, there was almost no difference to my misfire at all.

Could I have found the suspect possibly?

I intend to check out the MAS next week.

Any thoughts?
Robert

Did you try driving it with that disconnected to see if it makes a difference? Your check engine light is cleared now isn't it?

It made almost no difference...just a little shuddering when I came to a stop for a few seconds before the rpms were increased to compensate I assume.

Yes it was one of the 1st things I did that resolved a stalling issue.
