Question about Cars & Trucks

1 Answer

Lately my BMW Z3 Roadster will stall at traffic lights. It has even stalled when I am driving very slow. Sometimes the engine shudders when idle. I have also experienced the engine stalling for a second when I'm at crusing speed. What's wrong? Appreciate your advise

What have you checked, if anything? Have you noticed anything strange about idling (higher or lower than normal)? It could be many things, from something as simple as a dirty air filter, not allowing in enough air to the engine, to something wrong with the fuel pump. A vacuum leak is another possibility.

SOURCE: BMW 316i KEEPS STALLING WHEN SLOWING DOWN AT JUNCTIONS

at the engine, there is a small sensor that helps increase or decrease the rpm of the engine. Perhaps yours is soo low, that when you slow down, it's almost about to stop.

The other problem could be the airfilter sensor. If it's not properly fixed or if the sensor itself is a bit damaged, than the engine is not getting enough air and so, let's the engine almost go off.

Please give further details if this has not helped.

thank you

SOURCE: engine idles to low and stalls

Very similar problem, my car does not idle when i first start it. I have to keep my foot on the accelerator otherwise the RPM's drop to low and the motor stalls. I had a local Volvo dealer run a diagnostic (about $100 varies by shop). They said that it was the idle control valve motor.

The car has been robbed of the torque it once had and my MPG dropped from 28 to 21. You can find the part for around $170 on the web. The extra fuel costs were significantly higher than fixing the problem.

Prior to replacing this part I was able to manually adjust the trottle cable under the hood which helped with the car stalling. Be very careful when doing this, you can check your RPm gauge after making hte adjustment, I wouldn't adjust the throttle cable to the extent that the car idles over 1200 RPM, you'll still have to manually keep pressure on the accelerator for 2-3 minutes but after that the car should idle on it's own.

Hope this helps. Also, I love my volvo and there's nothing like a couple bottles of Octane Boost on top of a tank of premium. These motors are built for performance, try a high flow intake filter too, you'd be amazed how a few small changes like this dramatically improves the already great driving experience.

Have Fun, Joe.

1998 Z3.. Manual Trans shudder under acceleration in 2nd gear as it nears 2000 rpms, then goes away as it approaches 2500 rpm's.. Any suggestions?.. Thanks


It could either be the flex disc or drive shaft center bearing. I had the same problem on my 98 Z3 and I replaced both and it took care of the problem.

BMW Z3 3.0 year 2000 erratic tickover problems


You can in most cases repair this by cleaning the engine throttle valve and the idle speed control valve using a product called CRC Spray Throttle valve cleaner. Spray the cleaner into the air intake of the engine with the hose removed from the throttle body, the engine will try to stall so hold up the idle speed manually. Once you have used up about 1/2 can of the cleaner stall the engine out while spraying and turn the key off, disconnect the negative battery cable for 5 minutes and then reconnect and drive the car for a about 25 miles of varied driving modes. If this doesn't cure the problem you may need the fuel injectors professionally cleaned by the dealer service dept.

More then likely you need to change the spark plugs because they are fouling out. Thats the cheapest fix that I would do first! Then check coils.

I have a 99 BMW ROADSTER and I have changed


If there is a code for the Air Mass Sensor I would recommend replacing it. Also a common problem is the intake cam sensor going bad and not giving a fault but will cause the car to stall.
