Hi all, i have a 91 multi point EA manual.

When i pull up at a set of lights, for some reason my car just does not want to idle, it will just hang around the 1100-1400 mark, sometimes it will idle, others it will hunt between...

Any thing to check?

I am sure it is not vacume leek have sprayed WB40 around and has done nothing. Thank you

sounds like the car is in limp mode check the vacuum line to the map sensor and other sensors!

Thanks

Sometimes the idle control valves freaks-out at idle and create situations as you have described. Especially if a cam has been fiited. You could try disconnecting the idle control valve to see if the condition continues. If not, its related to the ICV. Sometimes they can be oversensitive and cause the revs to stay up after you use the throttle, usually at about 1300rpm for a few secs. You can stop this by making a plate from some thin aluminium that fits under the ICV and has holes only a few mm in dia where the big ones are.

Pretty common e-series problem

Sorry this is a late reply only just found this forum.

The fault is caused by the powersteering switch located onthe drivers side just by the steering colum.

Very common and easy to fix (With a short spanner)

Just thought i would post in case anyone else searches for the same fault

Yes,
i would check KIWI3D's suggestion...a common fault, often demostrates itself as hard to stop when going slow (like pulling up to the lights) and gives the feeling that the car is trying to outdrive the brakes.

Another common item is the throttle cable. Where it passes over the rocker cover it clips on. It is common to break there and prevent the accelerator from being fully released.
