Idling issue - again.....
Discussion
Evening All
Having been bugged by an intermittent idling problem since I bought the Chim back in Jan 2008, over the last couple of days something strange has happened. It seems that if I start the car from cold, until the engine is up to temperature, if I slow down for a junction the revs can dip/drop to the point of stalling.
However, I've also noticed that if I give the engine a few dips of the right foot as soon as its started, and take the revs past 4000rpm a few times, this issue doesnt seem to happen.
So my question - is this pure chance that some instant high revs seem to stabilise the tickover, or is it linked in with the engine management and initial engine set up once started??!
Any help / ideas much appreciated as always......
PS - Just for reference, lamdas have been checked and changed, ECU thermistor changed, stepper checked and changed, and corroded earth on wiring loom corrected. Coil pack looks like the original (1999) so was thinking that possible weak spark on cold engine could be a problem??!

From cold i assume
Have you replaced the plugs,cap,rotor arm,cap and leads there the easy stuff and then you can at least eliminate these at not a too great expense.

Has been to local specialist 4 times since Jan - the last time he was convinced it was sorted which was when he found the corroded earth connection on the engine block.
However, problem has recently reappeared, although now seems to be when engine is warming up.
To be honest, service was done in April, plugs changed, bearing in mind the issues, all other possibles checked (thats not to say that something else has started to play up in the meantime).
Just a post really to try and eliminate a few possibles and seek some advice. Love the car, just cant believe how difficult its proving to get it to idle without any issues......
