I have a 325es

I pretty much have the idle surging taken care of,but then when I take off it hesitates ,Till I hold a steddy peddle then its fine.

I replaced the fuel filter & hoses.Fuel presure's good
What do I look for first ?
Thanks

If you have newer plus, wires and cap. And there's no "check engine" light/code. The airflow meter may be sticking. Remove it from the intake hose and airbox and see if the flap inside moves freely without any sticking. If it's sticking use some carb cleaner to clean the pivot joints then apply some WD40 or CRC. If it's still sticking you'll need to remove the black plastic cover glued to the top and adjust the spring inside. This may be beyond your mechanical ability (consult Bently or other repair manual for the proper adjustment)
