Hi,

Thanks for the reply.
I found on the internet that there was a recall for a similar probleme but only for the 1.9 jtd engines. the solution was a complet reprogramation of the ECU.

I just boutgh an used butterfly valve on ebay. hope it will solve the probleme.
keep you posted

Hello, I have a probleme on my alfa gt 2l jts: slightly unstable idle I tried the throttle reset both manual an with FES but no change. I observed on FES with the key ON (engine OFF) the throttle degree varies slightly by 0.05 degrees. Does it mean the the butterfly valve is broken? Waiting for idea...
