engine is hunting

[JayDee]

You can unplug it, but you may have to adjust the idle up a bit using the screw on the throttle body. It is suppose to kill the cat if you do not have the pump connected, I do not see why as other cars run without a pump and it turns off at 3K anyway.

Will be removing cat soon anyway.  So its safe to just unplug it cool

hello have disconected  the air pump and now the car is hunting on idle.  The clutch on the aor pump is shaged as it still catchs tiny bit even with its unpluged?

Drop your idle now,the ecu is trying to settle it,but the screw will be too high,so they are both fighting each other.
If you are decatting then take the airpump off and run a shorter belt.
Don\'t forget that if you run no cat you may need an ecu upgrade.
