Unplugging one injector makes car run better???
My engine is idling rough when it warms up. Disconnecting number one cyl fuel injector smoothes it out a little bit. Is my injector leaking? Any input apprciated! TIA

I had this problem before. Check the resistance of each unplugged injector. They should all be close to the same at around 16 ohms or so. New injectors may be needed.

If you remove fuel from the engine and it runs better, that means you are running WAY rich!!!!!! :U
If you make the engine run better by removing a specific injector, that means that injector is leaking. Do a fuel system leak down test to see if you do in deed have a leak.
Check the spark plugs to see if one or all are burning rich.
