Hi,

I have a 1994 Mazda B-3000 that is idle surging. When I come to a stop the engine oscillates from normal idle to twice the rpm of idle. 2 seconds at a normal idle and 1 second at a high idle. Kinda like this…

_ _ _ _ _ _ _ *****_ _ _ _ _ _ _ *****_ _ _ _ _ _ _ ***** _ _ _ _ _ _ _

Anyone know what causes this and how to fix it?

Thanks

 

Hello Jeff
I just had something like this happen to my 2002 B3000. I had the mechanic change my plugs, wires and clean the throttle body. Problem solved.. no more surging and all kinds of "GO"
Hope this helps
