The car starts fine but when warmed up and slowing down for traffic lights the car stalls. the car will start again straight away but not idle . this problem is not always but annoying . please can someone help I have the same or very similar problem. I have a 1.3Ltr EFI 1993 Charade Hatch. It had been running perfectly, but the water pump seals gave out, so I have replaced the water pump and reconditioned the radiator. But what happens now is... that after about 5 minutes of driving (which gets it to about normal operating temp), it starts to rough idle. But it is more like its fast idle is turning on when its first started but not turning off and it revs up and down from around 550rpm to around 850rpm.
1. Check your water sensor and plenum temperature sensor.
2. The throttle body has a wax element air valve used for cold idle. As the water temperature increases, the wax element closes the idle fast port. Being the highest part of the coolant system you may have an air lock, which can be solved by bleeding the hoses on the throttle body.
The throttle body is the thing that sits between the air filter and the engine, You should see a couple of small rubber hoses going to it.
Yes the idea is to loosen one of the clips, pull the hose off and make sure water runs out of both openings (hose and the pipe it was connected to). You may have to give the engine a quick start (2 seconds) to get the water pressure up.
Hai..should I start the engine and then disconnect water hose or i disconnected water hose first and start or crank the engine for 2s.tqvm

Thanks for that.
I will go and check out what you have suggested in the next day or two.
I know this may be asking a lot, but would you have photos or drawings of what I need to be looking for? Or atleast the area I should be looking?
I have a fair idea where the throttle body is, when you say bleed the hoses on the throttle body...
Is that as simple as pulling them off and putting them back on? About how many hoses should there be?
Now this may be a dumb question...
Should I see something come out of the hoses?
Thanks for the direction...
Hi,
Sorry it has taken so long to get back to you, but we have moved house and internet during the last few weeks.
I have gone through and checked the sensors and one of the sensors was broken (snapped) obviously from when I put the radiator back in.
Now it looks like it is possibly the Thermo Fan Sensor.
There are some markings around the six sides of the hex nut.
They are: (1st side) = ND (which I guess is NipponDenso) (3rd side) = 6N10 (4th side) = 99M
The dealer pricing for the sensor is pretty expensive at $130.
I have looked at after market ones and have come up with two, but not sure if they are suitable and which one of the two is the right one as the temp ranges are different.
Once I get this replaced I will then be able to perform additional checks.
Many thanks.
I don't know if I mentioned it.
This is a 1.3Ltr G200S Charade.
Cheers
I have the same problem with my 94 model G200. I noticed if I disconnect the sensor up on the firewall in front of the driver, the idle returns to normal. Only problem is the 'check engine' dash light comes on and stays there. I tried bleeding the throttle body coolant, but it hasn't fixed the problem.
Could you describe where the sensor is on the firewall in front of the driver.
Is it in the engine bay or under the dash?
Is it easily found? Are you right hand drive?
I might try the same thing and see if I get the same results.
Atleast it might stop the engine surging when I am at the lights and people thinking I want to race them lol...
Cheers
Robert
