Plug in diagnostic computer for trouble codes if any.
Check condition of air filter, fuel filter and spark plugs and leads.

Aside from those listed above, other common causes of poor idle or stalling can include the manifold pressure sensor and especially the MAF (mass Air Flow sensor.)

    No DTC present. Maf will not cause the engine to die, run rich or lean yes but no cutting out will occur. Air filter, and fuel system are good.

    UPDATE for anyone else looking for a solution to this issue. It was MAP sensor that was at fault. To check it all you need to do is unplug it and see if any condition changes. If it doesnt then you have your problem solved.

My 2001 525td starts and drives ok but intermittently it wont go above 3000 rpm,if you stop and switch it off it goes ok again for a short while


HI, your car is most likely going into limp mode. The number one cause of this computer shut down restriction- is a Mass-Air Flow sensor malfunction. Fuel trims become erratic and the engine computer puts a order in to limit performance until the original problem is resolved. The fact that you can get performance back after shutting down car and restarting is that the computer is rebooting and most likely the sensor is now functioning properly and or has not set the number of faults required for limp mode. What I would do is have someone with a scanner look for DTC's or engine problem codes, and remember the following: Lean or Rich fuel trims detected bank 1 bank 2 (is a Mass Air flow problem)Replace Mass Air flow sensor assembly. Accelerator position high or low and or erratic is most likely (Pedal sensor) Replace Pedal assembly. Good Luck.

Stopped at light. Oil light came on engine died. Restarted no power real rough. Won't idle. Is there a safety shutoff on loss of oil press. Any suggestions. 1997 3.1 lumina


Hi. This issue has several causes, but the oil light indicator is a strong sign of low pressure in the engine. This will cause the engine lubrication rate to drop, thus, producing a illuminated oil light, and erratic Oil pressure readings. The necessary actions are to have a manual oil pressure test ran on this engine, asap. When running a manual oil pressure test, you will discover if the true oil pressure is low, or normal. If the test proves that the oil pressure is, indeed, low, this will confirm that the Oil pump is suspect.

Now, if the true readings given during the manual oil pressure test are indicating that the pressure is normal, this will be the result of a failed sending unit(oil pressure switch). Although the oil pressure is suspect, this is not your only issue here. There seems to be a abnormal compression rate, present. This is causing the rough idle, and erratic RPMs. I recommend to administer a engine block compression test, as well. This test will discover if , indeed, there are issues within the cylinder heads, and block structure, such as a worn head gasket, cylinder wall issues, and cracked block. Normally, these issue will send signs, like white, or gray smoke out the tail pipe, or discolored oil. It will, also, promote erratic RPM ratings, and a rough idle. Have the oil pressure test, and engine block compression test ran, asap.

Once the test are administered, you will be able to isolate the actual problem areas, more accurately. Check the spark plug wire sets, and ignition assembly for faults, also...

Vacuum leaks. Check all hoses and intake bolts. Leaking EGR or plugged PCV valve. Air filter plugged. Leaking head gasket. Worn timing chain. Camshaft lobes worn. Valves burned or leaking. Fuel idle control system or sensor. Good luck!

Idle problem


Try to disconnect the Air Flow Meter. It is the first plug just before the air filter/air intake box. If this improves your situation you will need to source a new or aftermarket Air Flow Meter.
