Corsa 1.6 cannot maintain idling

nc1bad · 13th November 2009, 20:24

Dear All,
I own a 1.6 corsa and am facing a major problem with the vehicle and need urgent assistance.
The vehicle is unable to maintain idling during running / using the vehicle, meaning, the engine switches off when the clutch is pressed during
traffic, turning etc. The service center guys are not able to find the source of the problem and made me change parts unnecessarly.
Parts changed by trial and error method:
1. Ignition Coil
2. Fuel Pump

If anyone knows or has faced a similar problem like this, i would appreciate all the help i can get.Thanks

The above problem may occur if the vehicles battery was discharged. Did the service center guys check the battery?

Or the symptom may also occur if there is air intake leak.

Fuel pump CHANGED because the car won't idle? That's the wierdest... But there can be multiple issues causing this, and need to be eliminated one at a time. The list goes from common to uncommon but does not include everything.
1. Bad petrol/water in petrol
2. EGR valve stuck open
3. Spark plug/plug leads (open and check how they look)
4. Injectors (try using System-G or similar first)
5. Timing belt
6. Valves

Can some others also confirm weak battery as the cause of this problem? I am also facing the same problem in Xeta-cng. My battery is still original and the car is 3 years and 60,000km old. Should I also take a look at the plug cables?

Idle control valve, attached to the TB. remove, it and clean it by spraying a Carb/TB cleaner on it, a fine clean cloth to dry it . If it does not help then the ICV might have to be changed.

The IDV is cleaned during routine throttle body cleaning, right?

I would hope so, but its hard to trust some mechanics. You could check to see if a TB has been cleaned ( to some extent ), but Idle Control Valve would not be possible to tell by merely looking(without dismantling). So, I am sure, most of the mechanics would skip it if the car does not hav idling problem. Either because they are lazy or have too many cars to fix in a day.

hi guys, sorry for the delay but i wanted to be 100% sure before posting.
The problem is solved, i changed the TDC sensor (costs Rs 1500) and the vehicle is now running smooth.

false alarm guys the problem still persists. help needed!

Dude, get the crank sensor checked . does problem occur with AC switch on only? if so the feedback loop to the ECM has to be checked.
