<P>Alasdair,</P>
<P>There are a lot of things that could affect your idle - I just went through this whole ordeal myself. First, check your idle stabilizer valve: turn on the ignition, but don't turn over the engine - you should hear/feel the ISV buzzing. You can also check the harness that plugs into it for continuity. If that is fine, check the ISCU - its behind the rear passenger side taillight. If its not the "B" version, you should replace it anyway. See if it looks burnt at all or if wiring for its harness is damaged at all. Check for continuity coming from it -all this info is in the Bentley. If the ISV and ISCU are okay, then look for air leaks - exhaust, etc. Check the oxygen sensor. Check your throttle valve - check for continuity and make sure the throttle is set properly. And finally, my problem ended up being a bad throttle
cable which wasn't apparent at first until it gradually got worse and my gas pedal started sticking in the acceleration mode. The first time I had this problem though it was the ISV, so start there. There is alot of information on this problem in the archives as well - its pretty common.</P>
<P>Good luck,</P>
