SOURCE: Describe your BMW 2001 325 Problem car hesitates

this problem could be cause by a few things, the first thing to check would be the operation of the air fuel sensor and the next thing i would look at would be to check for proper fuel preasure. the preasure spec is 50psi. and the volume spec is that it should pump at least 1.85 L in 30secs.

Is the heater control in the defrost position? Most cars will automatically turn the air conditioning compressor on when defrost is selected to dehumidify the air being directed on the windshield. This keeps the windshield from fogging up, and helps defog the windshield more quickly if it is already fogged up.

Testimonial: "Thank you for your answer Then what does the heater control in the defrost posision mean? Just turn on air flow to front( There are 3 positions-upper/front/under)"
