It is unlikely to have been like that at manufacture, and is more likely to have been a repair in the past which Wed, 30 Sep 2009 17:36:25 GMT Miklos Koleszar http://uk.groups.yahoo.com/group/mazda626uk/message/2668 http://uk.groups.yahoo.com/group/mazda626uk/message/2668 John, I spent ages looking for air leak, but found none. But I did find this below, which ahs to be a first: I seem to have cured the idle problem.

I seem to have cured the idle problem. The solution has been too simple to contemplate. Some 3 weeks ago i first noticed that there is a rubber Sat, 26 Sep 2009 08:08:40 GMT compyshop http://uk.groups.yahoo.com/group/mazda626uk/message/2666 http://uk.groups.yahoo.com/group/mazda626uk/message/2666 Hi Kev.. Well to be honest, most problems of this nature are down to a small air leak.. either from cracked rubber pipes, loose or disconnected pipes, or leaks Sat, 26 Sep 2009 05:38:59 GMT kevfal0 http://uk.groups.yahoo.com/group/mazda626uk/message/2665 http://uk.groups.yahoo.com/group/mazda626uk/message/2665 hi, I had similar problems with a rough idle when the car had warmed up. i replaced the air intake manifold gasket and the problem was solved. i have a 2000 gf Fri, 18 Sep 2009 22:07:53 GMT Miklos Koleszar http://uk.groups.yahoo.com/group/mazda626uk/message/2664 http://uk.groups.yahoo.com/group/mazda626uk/message/2664 Thanks for the suggestion, Pete.
