If you need help retrieving codes you can find all info on tech center pages. Regards, Zig.
Actually, if it runs fine when it's cold then you have a sensor issue once it starts running closed loop. Check to see if you have any codes before spending the money on an injector flush. O2 sensor perhaps? I had a similar issue on my C4 that was an O2. Check for codes first.
