Motor cuts out intermitantly nothing on fault codes or scan tool fuel preasure low have replaced fuel pump cleaned air flow

Check and clean mass air flow sensor according to directions on can. BE VERY CAREFUL< THIS SENSOR IS VERY DELICATE. Hope this helps.

A it's starting to run rough and stall what happens if you spray a little carb spray into the throttle body? Will the idle smooth out?

many things cause intermittently stalling if you see check engine flashing on code scan for faulty mass air flow sensor.faulty idle air control valve or egr solenoid.could have bad spark plugs and wires faulty fuel injector. contaminated fuel restricted fuel filter or fuel pump failing. faulty TCC solenoid .

code scan if you see check engine light flashing.but the exclamation light mean low tire pressure.engine stalling out could be faulty idle speed control.bad fuel injector or ignition coil.could be faulty mass air flow sensor.have vechicle code scan could be low on fuel or faulty fuel pump.

Hello
The Engine and Automatic Transmission (not applicable to manual transmissions) in this vehicles drive train are fully electronically controlled by a computer called the PCM and TCM (Power Train Control Module, Transmission Control Module). When a problem like this or other drive-ability related problems occurs the computer stores a record of the problem (there are of course some exceptions to this, like the fuel pump, engine coolant temperature sensor and MAF sensor for instance) in the form of a fault code in its memory, to read these fault codes you must have the systems memory scanned with a special tool. Once the fault code(s) are read you then must perform the appropriate diagnostic testing to find and resolve the problem(s) DO NOT REPLACE ANY PARTS UNTIL A TRAINED TECHNICAIN HAS DIAGNOSED THE PROBLEM TO AVOID SPENDING YOUR HARD EARNED MONEY ON PARTS THAT MAY NOT CORRECT THE PROBLEM. Also always check fuel pressure for correct spec for your make and engine type.

Have you tried to replace the fuel filter.....sometimes this inexpensive item is often overlooked! It is possible you have some debris in it that gets in the way intermittently and cuts off the flow! If you found this answer helpful please vote so! Thanks

Have you run fuel injector cleaner through the fuel system?

FIRST CHECK FUEL PREASURE (I THINK ABOUT 3,3 BAR).IF OK, CHANGE AIR FLOW SENSOR.
MARKO

reset fuel pump enersha switch in trunk?

BMW CUTS OUT
A few things to check.

1. Is fuel pump delivering enough fuel.
2. Is injectors clean. Perhaps dirt in fuel. replace fuel filter
3. Air leakage at top air intake of manifold at ICV idle control valve. Two hoses inside this housing prone to perishing.
4. Throttle position sensor faulty.
5. Mass air flow sensor faulty.
6. ICV faulty or dirty. comon fault on older e36.

Havent done it yet but ICV is easy to clean according to internet. instruction available at bmw e36 blog. All off above can be tested by yourself according to manual.
