96 2.0 Dohc Galaxy Random Stalling Help ?

[Guest lost_galaxy]

Hi,
I've got a 96 2.0 DOHC Galaxy. If it's stood at tickover, it will stall if the throttle is 'blipped'. It also cuts out when approaching junctions - if you depress the clutch, apply the brakes the engine will stall almost immediately. I think the AIR / EGR systems may be at fault, or maybe the TPS or IAC valve. Any ideas ????

Hi

I'm afraid that I don't have an answer - but I do have the same problem.
It doesn't occur all the time on my 96 2.0; but periodically it goes through a patch of cutting out for no apparent reason as I slow down for junctions or corners. So there's two of us who would appreciate any wisdom!

Hi guys!

My 2.3 zetec was doing the same, and I traced it to the idle speed control valve. Just a matter of taking it off and cleaning out with WD40 until the piston inside moves up and down freely! Hope this helps you both!

Definitely sounds that its the idle speed control valve. I used to have a vectra and the valve used to fail every 2 months. Crap cheap parts used in construction. Vauxhall charge

Poor idle speed control/Stalling - Petrol vehicles
Usually caused by a gummed up Idle Air Control (IAC) Valve. This valve allows variable quantities of air to bypass the throttle plate to control idle speed, fast idle and prevents the engine revs from dropping too soon on decellaration. On the 2.0 and 2.3 Ford engines, the Valve is easy to remove once the injector connectors are disconnected. Remember to disconnect the battery earth lead first (know your Radio Code?). Unbolt the IAC from the throttle body and clean the slide thoroughly with Carb Cleaner. Before replacing, lightly lube the slide with WD40, and replace the small face seals if damaged or worn.

Note: The engine will run differently for at least 50 miles until the ECU has "re-learnt" the live parameters particular to your engine. Idle speed control included. This is characteristic of adaptive engine management.

Also, there is a screw to adjust the throttle plate rest position. DO NOT adjust this to compensate for a poor idle speed control. If some misguided soul has played with this, it can be set. Email me for more.

Other causes of poor idle control (apart from engine damage or wear) are: intake air leaks, particularly from split hoses; defective EGR valve; blocked Cat; faults in the secondary air system.

Good idle control only when hot or cold can also be caused by a faulty coolant temp sensor, although this is usually accompanied by severe drivablility problems.

Before I got my galaxy i had a peugot 405, it had the same problem. It ran OK at high revs but approaching junctions/roundabouts or when it was idleing it would stall. I managed to cope with this by using the handbrake to slow down so I could always keep my foot on the throttle. When I took it to a garage they said it was the engine management computer. I had the 'black box' replaced and it still runs perfectley as far as I know.

p.s just a possibility.
