Question about 2001 BMW 5 Series

1 Answer

X5 2001 4.4i - rough on low down acceleration at medium pedal press. idle at accelerate is fine, only under acceleration. At higher speeds is fine and no spluttering. When I put in drive, put foot on brake at a standstill and accelerate the problem is noticeable. It has no issues changing or selecting gears so transmission seems fine. It has only just started doing this. It has 100k miles on it. Have not done anything yet...thanks

Sounds like lack of preventative maintenance

Spark Plugs every 3 years or 30 to 40,000 miles

You may have ignition coils failing

Clean MAF Sensor

Replace any O2 Sensors over 100,000 miles

Gas filter every 3 years

The first thing to do is to check the transmission fluid level as some of your symptoms are classic for low fluid levels.

Engine idle very lumpy and wanting to stall on gear down shift. Sometimes poor on starting until fuel gets through then car runs well but very smelly.


SYMPTOM 1: ROUGH IDLE IN THE COLD

The engine will not idle smoothly, or it stalls during idle when the engine is cold. When the engine is cold and you take your foot off the gas pedal, the engine runs very rough and may even stall. When you run the engine at higher speeds, it seems to run fine, or at least it runs more smoothly.
Possible causes:
  1. If you have a carburetor, you may have a bad accelerator pump or power circuit.
    The Fix: Replace accelerator pump or replace the carburetor.
  2. There may be a vacuum leak.
    The Fix: Check and replace the vacuum lines as required.
  3. There may be some type of ignition problem.
    The Fix: Check and replace the distributor cap, rotor, ignition wires, and spark plugs.
  4. The ignition timing may be set wrong.
    The Fix: Adjust the ignition timing.
  5. There may be a fault in the computerized engine control system.
    The Fix: Check engine control systems with a scan tool. Test the circuits and repair or replace components as required.
  1. The EGR valve may be bad.
    The Fix: Replace the EGR valve.
  2. The engine may have mechanical problems.
    The Fix: Check the compression to determine the engine's condition.
  3. Idle speed is set incorrectly.
    The Fix: Set idle speed to the car's original settings.
  4. The fuel injectors may be dirty.
    The Fix: Clean or replace the fuel injectors.

SYMPTOM 2: ROUGH IDLE WITH WARM ENGINE

The engine will not idle smoothly, or it stalls during idle when the engine is warm. When the engine is warm or hot and you take your foot off the gas pedal, the engine runs very rough and may even stall. When you run the engine at higher speeds, it seems to run fine.
Possible causes:
  1. If you have a carburetor, you may have a bad accelerator pump or power circuit.
    The Fix: Replace accelerator pump or replace the carburetor.
  2. There may be a vacuum leak.
    The Fix: Check and replace vacuum lines as required.
  3. The fuel pressure regulator may be operating at too low a pressure.
    The Fix: Check the fuel pressure with a fuel pressure gauge. Replace fuel pressure regulator. (This is not really a do-it-yourself kind of job.)
  4. Idle speed set incorrectly.
    The Fix: Set idle speed to specs.
  5. There may be some type of ignition problem.
    The Fix: Check and replace distributor cap, rotor, ignition wires and spark plugs.
  6. There may be a fault in the computerized engine control system.
    The Fix: Check engine control systems with a scan tool. Test circuits and repair or replace components as required. (This is not really a do-it-yourself kind of job.)
  7. The EGR valve may be bad.
    The Fix: Replace EGR valve.
  1. The engine may have mechanical problems.
    The Fix: Check compression to determine engine condition.
  2. The fuel injectors may be dirty.
    The Fix: Clean or replace fuel injectors.

SYMPTOM 3: FAST IDLING

The engine idles too fast. After the engine has run long enough to become warm, the idle speed does not come down to normal. You really notice it when you come to a stop and must have to push ******* the brake pedal to keep the car from moving.
Possible causes:
  1. If you have a carburetor, you may have a bad accelerator pump or power circuit.
    The Fix: Replace the accelerator pump or replace the carburetor.
  2. The engine may be overheating.
    The Fix: Check and repair the cooling system.
  3. The fuel pressure regulator may be operating at too low a pressure.
    The Fix: Check fuel pressure with a fuel pressure gauge. Replace fuel pressure regulator. (This is not really a do-it-yourself kind of job.)
  1. The ignition timing may be set wrong.
    The Fix: Adjust the ignition timing.
  2. There may be some type of ignition problem.
    The Fix: Check and replace the distributor cap, rotor, ignition wires and spark plugs.
  3. There may be a fault in the computerized engine control system.
    The Fix: Check the engine control systems with a scan tool. Test the circuits and repair or replace the components as required.
  4. There may be a vacuum leak.
    The Fix: Check and replace vacuum lines as required.
  5. You have a bad idle speed control unit.
    The Fix: Replace the idle speed control unit.
  6. The alternator may not be working properly.
    The Fix: Replace the alternator.

SYMPTOM 4: STALLING UPON STOPPING

Car stalls when stopped quickly. You are driving along and everything is just fine ... until you let off the gas pedal and apply the brakes. The engine starts shaking and may even stall. Not a good thing to happen because you lose power steering when the engine dies and could risk an accident.
Possible causes:
  1. There may be a serious vacuum leak.
    The Fix: Check and replace the vacuum lines as required.
  2. There may be a fault in the computerized engine control system.
    The Fix: Check the engine control systems with a scan tool. Test the circuits and repair or replace the components as required. (This is not really a do-it-yourself kind of job.)
  3. Broken linkage.
    The Fix: Repair or replace the linkage as required.
Idling issues can be very frustrating, but with some patient troubleshooting, you'll have a real chance at figuring it out. Remember to always check your engine idle with the air conditioning and defroster turned off, as both of these systems are designed to change the idle when they are on due to the air conditioning system's demands on the engine.

Whistling noise under slight acceleration


check for a cracked manifold or cracked flex section at the manifold
it is under load so it is not a vacuum leak as the vacuum is low under acceleration and high under deceleration or idle
indicates a gas leak or possible blockage from failed cat converter

Why did my engine stop accelerating just stay at idle


Your accelerator pedal is bad. The IVS (Idle Validation Switch) is probably not shutting off, or the potentiometer in the pedal went bad.
Hopefully you do not have adjustable pedals as the pedal assy. can be expensive for those.

2006 Saturn vue, 4 cylinder. Ran out of gas, couple gallons put in, ran fine. Went to gas station filled up full. Driving home, noticed my reduced power indicator flashed a few times on then off. Once...


reduced power , electronic throttle control problem . Reduced Engine Power Mode
When the ECM detects a condition with the TAC system, the ECM may enter a reduced engine power mode. Reduced engine power may cause one or more of the following conditions:
• Acceleration limiting--The ECM will continue to use the accelerator pedal for throttle control; however, the vehicle acceleration is limited.
• Limited throttle mode--The ECM will continue to use the accelerator pedal for throttle control; however, the maximum throttle opening is limited.
• Throttle default mode--The ECM will turn off the throttle actuator motor and the throttle will return to the spring loaded default position.
• Forced idle mode--The ECM will perform the following actions:
- Limit engine speed to idle by positioning the throttle position, or by controlling the fuel and spark if the throttle is turned off.
- Ignore the accelerator pedal input.
• Engine shutdown mode--The ECM will disable fuel and de-energize the throttle actuator.

Engine runs rough after about ten minutes /idles really low


Just trowing some suggestions out there, but, I would check the idle air control valve (solenoid) or the throttle position sensor. If they check out then my last guess would be the map sensor or the vaccuum to the map sensor. Hope I was able to help. Best wishes.
