Help! Poorly Valver

[madmat]

I need some help! For the last few days the car has been cutting out at idle speed having been driven around. It idles at the correct speed but just keeps cutting out. WHen you try to restart it it seems that the engine has been flooded and takes a while. Its not realy driveable. If anyones got any ideas it would be appreciated.

My first guess would have been Idle Speed Control Valve but as you say it idles fine but just cuts out. Wont be anything serious anyway, just a faulty sensor somewhere....lambda/TPS maybe?

You dont have a power boost valve on it do you? Could be that....

possibly:-

tdc sensor(tdc sensors normally fail when they get hot)

idle valve

Thanks it could be that tdc sensor then because the coolant hose split so there was some major overheating. Ill give it a shot

Where/what is a tdc? (Prob a dumb question! )

TDC or top dead centre sensor is located at 0 degress on teh flywheel. It reads the teeth on the flywheel to provide the ECU with Crank position information.

Also referred to as CAS

on the top of the gearbox bell housing held in place by two 10m bolts.the tdc sensor is used so the ecu knows the engine position and can inject etc at the correct time on the correct cylinder.the flywheel has 2 marks on it one of which is engine tdc.the other mark is used so the ecu can advance etc the timing.it checks the timing has advanced etc enough by counting the teeth between the two marks.
