V50 1.8l 2006 Engine stall, swaying rpm at neutral
Hi experts, I am new in the forum, please help.
Symptoms: 1. After engine started, rpm drops till too low that it stops, especially in cold weather. If the temperature is above zero, the engine will choke (sounds like it will die at any time) at low rpm for some time after started, then comes back to normal around 1000. 2. After the engine started and rpm comes to normal, before driving off the car, touching the gas pedal slightly by foot, I found the rpm drops slightly by 100, then giving harder press on the pedal, the rpm rises as normal. 3. Now drive the to the road, at some point put the gear to neutral position and let the car slide. I heard and found the rpm swings between 1500 and 200 continuously. Pressing down the clutch, rpm becomes stable as normal. All above mentioned symptoms disappear after 5km running when the engine is hot. I have done some homework search and it seems the problem could be: idle control motor, crank position sensor, MAF and oxygen sensor, fuel pressure regulator, etc. I don't think cleaning the throttle body can solve the problems for long term. Before homework search I have stupidly spent lots of money at local dealer getting the gas pedal changed, and temperature sensor cleaned, etc, so that no more fault indicator light is on in dashboard, but all problems still exist! Could someone kindly help me out with these annoying faults? What should I really do with little money left and an angry wife? Thanks! |
For parts 1 & 2 I'd have thought the throttle body would have been to blame and requires a clean/replacement.
For part 3, this makes it sound like you have a clutch/DMF problem. :star-wars-smiley-01 |

Greetings from Denmark. I have the exact same issue, i took off the throttlebody and cleaned it thoroughly, and inspected the gear and the small electric motor that drives the flap on the throttle-body, all seems fine. Nevertheless the cleaning did not solve my problem. I was wondering if you found a solution to the problem ? Cheers. |

I my mind i could not see why the throttle body in all cases should be changed(as many people and mechanics say). After a cleaning it looked brand new, furthermore since there was no "slack/play" in the barrings, and no errors from the sensor, a software bug seems very likely :). Cheers |
