Hi Jim,
Not sure about that, don't know what you mean by throttle pot,
hopefully Steve will respond.
At the moment the car is in Aylesbury but has been at Steve's
near Woking.
Geoff.

Did you do any electrical tests on the throttle pot.
Where is the car ?

Hi all and thanks again for all the helpful suggestions.
Steve and I have checked and double checked through all that
has been suggested, every thing seems to work as it should
individually. The idle speed control vale has been
thoroughly cleaned again and checked to see that it works,
then refitted with a new gasket and that it receives input,
electronically, from its plug. Steve has checked all the
connections with his testing equipment, it's all beyond me!,
and it all works. We have reset the ECU yet again, despite
spending all day Saturday trying to get it to run properly,
it still has the same problem.
Thank you Steve for all the time and effort you have put in
so far to try and fix it.
So if any of you have any further suggestions, we would be
pleased to hear them, as Carole and I are getting worried
now, with only one weekend to go before we head to Scotland.
Yours hopefully Geoff.

Thank you to all for your help and advice, I will do a
bit more checking and cleaning of contacts etc
tomorrow. The strangest thing,as Steve mentioned in his
original post, is that the engine idles perfectly
at around 900 - 1000 rpm (according to the XR2 rev
counter) when you first start it up. I have followed the
method for resetting the ECU 4 times know and it has had
good idle speed every time for the first stage of the
reset, ie allow to idle for 10 -15 mins (DO NOT TOUCH
THE THROTTLE) it only goes all wrong after that! As soon
as you start to drive it, that's when it wont idle
properly anymore.
Carole say thank you all.
Regards, Geoff.

We're getting a very bad idle with the Zetec in
Carole's 2+2. With the idle
speed control valve connected from cold it will idle
nicely at around
1000rpm, if just left to idle and warm through.
However if you rev, or
drive that car the best idle to can get is between
2-3,000 rpm, which isn't
great :( The car also drives badly, having
hesitation and then you fight
the engine on the over run.
It is a lot better with the ISCV disconnected, but
still not great. The
idle is still a bit high, being around 1,200 rpm and
it still doesn't drive
that great.
We've tried resetting the ECU to re-program it and
Geoff's cleaned all the
electrical contact and the ISCV. Any ideas what
else needs to be done to
get this ready before the HHII?
Regards,
Steve
