Hi,
Ive been having this problem for a while.
Basically what happens is when pulling up at a junction or roundabout etc, the engine revs drop to a normal idle. Sometimes then the engine cuts out.
It doesnt do it very often around once in a 40 mile trip. and it is usually after the engine has not been at idle for a while. When it cuts out the warning light under the petrol warning light comes on (like a coil), the ECU or whatever tries to stop the engine stalling but never suceeds, it revs it automatically. At this point stalling can be prevented by pressing the throttle. The car will then drive normally.
I took the car into my local garage. Which is an independant garage
First of all they suggested it was the Idle control valve, which seemed logical to me so I left them with it. When I went to pick the car up they told me that they didnt think it was the idle control valve as the stalling was fairly rare and he said usually with an idle control valve the engine would cut out everytime the engine was at idle.
They told me that there was a multiwire connector at the back of the engine that he removed and found the contacts were slightly corroded, cleaned them up with electrical contact cleaner and they thought this was the problem.
However the engine stalled three times in the 40 mile trip home. I took it back to the garage and they put it on their code reader. The codes that were on it were cleared. I was given the car back yet again to test. It stalled again once on the way home.
The next day they put it back onto their code reader and a fault code came up saying the engine wiring system was at fault. Which convinced the mechanic that this multipoint plug was at fault.
Im not convinced that a poor connection on this plug would cause the problems.
I think the garage has ran out of ideas, they said that using an electrical contact cleaner that improves connectivity would be their next step.
I just wanted any other views, Is this connector on the engine a common fault?
