Problems outlined below.....

Car starts fine, idles reasonably fine when cold.

Once warmed up and pulling up to a stop idle stays at either 2200rpm (drops to 1400 if you load car a little but more often just dies completely
and playing with the accelerator doesn't keep it going, it just diesbut then restarts fine.

I don't think the distributor advance is the issue as timing has been triple checked and it advances when it should.

Just wondering anyone else suffered the same symptoms.
