I have the idle bounce problem talked about in the FAQ section but i have cleaned the ICV and replaced both the o2 and temperature sensors with no luck.

The gas analyser says its running rich but i've run out of ideas to what it could be.

Any help would be appreciated

do you do your own maintanance? ive heard of a lot of shops saying they replace things but they really dont, check your spark plugs my dads friend had a wild a idle problem it was that the spark plugs were never changed.

I have the same issue with my engine.
Ive done all you have done so far, and have even replaced the MAF sensor and did not do much os a change.
What i did last month and seemed to help was to use a fuel injector cleaner. Apperantly when the injectors on this car gets dirty, or some deposits, they tend to let more fuel go in.. Look on google for a gold system fuel injector system, is something called like that. it comes on a gold looking can and you put it on the gas, is a very concentrated fuel injector cleaner, therefore i recomend doing this before changing your oil, since this tends to dilute your engines oil.

Anyway i used the chevron fuel injector cleaner and i did some help, but as soon as my next oil change comes i will try the gold can.
let me know if you do this and tell me how it goes. thanks]

Victor

Thanks, my Mechanic thinks you could be right and has even suggested taking the head off for a full clean, but i think i'll try your suggestion first.

I let you know what happens

Cool, Let me know what it does, i know that there is places that you can send your injectors and they clean them for you. Also you could clean them yourself in case you have an ultrasound machine,,, anyway i dont thjink you need to remove the head, as normally i doubt the valves get carbonazed with such mileage,

keep us posted.
