Adjusting Idle Speed Higher?
 

How is this done on an 07 2.3L? Mine seems to idle at 600rpm, bounced around and stalled on the freeway today.

Thanks

Tina, did you ever figure out how to increase your idle speed on your Mazda 3 2007?

Apparently the idle is controlled by the ECU so it cannot be manually adjusted.

possibly, one of the few things a voltage stabilizer/groundwire kit might actually help....

if your car stalls it probably needs an pcm update to solve the irratic idle and stalling issues.
