>Hi everyone,
>I need help on an 84 325e which hesitates on acceleration only when

>Replaced - Spark plugs, Air intake Boot, Valve cover gasket, 
>Transfer Pump, O2 sensor (which solved idle problems)
>I've tried two different brands of injector cleaner.  Cleaned the
>intake/throttle plate.  I've tried the easy stuff too like...different brand
>gasoline, checked for air intake leaks, and tested Air Flow sensor 
>(whatever it's called).  I'm kind of lost now on what could cause

>Any response would be greatly appreciated.  Thanks.

Brian-
you might want to check distributor cap and ignition wires. valves might
need adjusting too.
