Describe your BMW 2001 325 Problem car hesitates

IT DOES SOUND LIKE KEY FOB DYING AND I HOPE IT IS AS IT WOULD BE CHEAPEST PROBLEM TO SOLVE. GOOD LUCK

It really sounds like you have a belt that is worn out and slipping. This will cause both of the symptoms you describe. Have the belts checked.

Check fuel pressure. If good, rebuild carb.

you need a noise filter the radio is getting interferince from the motor

One of the wires in the circuit is loose, or a fused link is defective. Check all fasteners and connectors to make sure they are secure. Spray a small amount of lithium grease on the connectors to ensure that they connect fully - your intermittent problem is due to intermittent contact.

sound like throttle position sensor.have it check out.also check air duct connected to mass air flow sensor and throttle body.if air duct is loose or off.it will cause severe hesitation.

change the fuel you are using. try some fuel system cleaner. this is a petty issue, every vehicle develops issues over time.a bmw owner complains about hestitations, a bmw driver enjoys the ride. DEAL WITH IT!!!

That was just a generic answer I do not know your particular car. Back in the day we put oil around the intake gaskets and if the engine  speed increased or steaded we knew that we had found it. I also could be other things.  Have you tried Carb/injector cleaner in with the gasoline? A vacuum leak could be too small to show on a vacuum gage but a person could look for or at least confirm a leak with the gage. Sorry I can not be of more help.

This could the problem with on board computer please get it checked..............

What is your question...?
