Question about 2003 BMW 325

1 Answer

Air sucking noise from below the intake manifold.

Just bought a 2002 325i. The car runs great, no engine light. The air induction sound seems a little loud on easy acceleration, I hear an air sucking noise coming from under the intake manifold. any ideas what might be causing the noise?

Where is IAT sensor located


The intake air temp sensor is located at the intake, on the same large hose as your air filter. After the filter. Its measuring the air temp of air going in to your engine.

The engine light went on 3 separate times . It said the # 1,2,and 3 cylinders were misfiring . So I replaced the original coils on all three and it seemed to run good after that for about a week. Now it's...


It could be a lot of things. I would start by checking for air or vacuum leaks. Check the intake manifold gasket for a leak. Use a spray bottle filled with water. With the engine running, wet down the manifold gasket areas. If it is leaking, the water will get sucked into the manifold and engine will stumble or the idle pitch will change. May even try to stall, keep it running at a high idle while you are spraying, and listen for a change in idle speed.
Also check vacuum lines and the big air boot between the air filter housing and the throttle body-cracks or tears in the boot may let unmetered air into the intake.

1987 Chevy Silverado Fuel/Oxygen Problem


it seems you have already replaced sensors related to air/fuel mixture.
You need to check for vacuum leaks. If there is a leak after your maf sensor, ( a crack on intake manifold or related things like rubber hoses etc)
engine sucks more air than calculated by ECU(so o2 sensor reads lots of oxygen and gives error TPS thinks it is open wider than it should). this is actually extremely lean mixture situation. when you step on gas engine sucks more air than it requires actually and stalls.

to prevent this you need to find the source of vacuum leak. spray some brake pad cleaner to intake manifold (not to filter housing) try to hear the sound difference in engine. if it happens it means it is sucking cleaner inside engine.

give it a try.

CHECK ENGINE LIGHT ON ECU COD INTAKE VACUM LEAK WHAT IS MOST COM PROBLEM WITH THE 2.5 AND VACUM LEAK


Hello...

I am not sure about your exact car. Im sorry, but I dont know EVERYTHING. However most vac leaks are caused by a hose. If not the hose then by a loose intake manifold, or bad manifold gasket. Sometimes the manifold itself can crack.

The EASIEST way I have found to run down a vac leak is to buy a can of SPRAY carb cleaner, most autoparts stores have this stuff. With the engine running spray the carb cleaner near suspected leak sites. The ends of hoses, down along the intake gaskets, pretty much anywhere air can go. When you find the leak your engine will SPUTTER. Sometimes it will even die. Carb cleaner doesnt burn that great apparantly and when it gets SUCKED IN to the fuel air mix it throws it off.

Once you find the site of your leak the fixes are pretty easy. From what I have read recently alot of people seem to be getting away with just tightening bolts this winter. I dont know if the sudden change in temp or just everyones cars seem to be about the same age.

Anyhow thats how I find intake leaks.

I hope this helps

Why does my 2001 Ford Escort run rough and often die at an idle but seems fine oncethe RPMs are up?


There are two likely possibilities. One is a leaking vacuum line. Inspect the vacuum hoses closely. Listen for any tell-tale hissing sound. Oftentimes the culprit is the hose going from the PCV valve to the intake manifold. It is susceptible to cracking. While you're at it, check the condition of the PCV valve.

The other possibility is a faulty Idle Air Control (IDAC) valve. If the IDAC is not opening sufficiently, the engine will idle rough or die at idle. Try removing the IDAC entirely, so the air intake is open. If the engine idles ok with the IDAC removed, replace it with a new IDAC.

If neither one of these possibilities checks out, you will need further trouble-shooting.

Idel issue after air intake install


Your problem sounds like have air leakage from air induction system. I suggest you to re-check the gasket of Air Intake Manifold you installled or vacuum hoses for possible air leaking.
The easy way to check it, use Throttle Body or Carburator Spray Cleaner. Just spray around intake manifold where gaskets fitted and observe the idle speed, once the idle change or encrease, definetly there is air leak and you have check the gasket or replce it if necessary.
But if doesn't make change, I suggest you to check Idle Air Control Valve, check connector plug, lines and if you have donor unit try to do test part.
I hope you fix your problem and please update me whatever the result if you dont mind. Thanks

When engine is running there is a high noise, when shut off there is a sucking noise stops after a few seconds. noise seems to be coming from driver side on the back of the engine. This is a California car


Check the big rubber hose/pipe between the air box and the inlet manifold for cracks or splits.
Sounds like its sucking air.
While your at it check all the hose's/Pipes that connect to the inlet manifold.

I'll try, 1st let look at the air being sucked in, the area you are describing sounds like where the plug wires are. The only tube that can leak air (sucking in noise) in this area is the intake tube that goes between the intake manifold and the air filter, if this hose has a big leak it will make that sucking in sound, it will also prevent air from going through the Mass Air Flow sensor (MAF). This will cause the engine to run poorly. Check the intake hose if it is cracked, got a hole in it, then replace it. Hope this helps, let me know.

High idle


That sounds like an air leak. With the engine running listen for a high pitched whistle around the induction area, if you think you have found one spray a little WD40 in the area, if the WD40 gets sucked into the air leak your engine will run rough for a couple of seconds while it burns off the WD40 and that will confirm an air leak in the area you sprayed the WD40.
