Rough idle

Hi, I am still having problems with my c3. 1.4 petrol, when 1st starting it has a rough idle, for about 1 min.then it clears, turn it off, restart and the same thing. I have connected Lexia and no codes, looking at it while the engine is running, it rough idles in open loop, as soon as it goes to closed loop, perfect. I have chaged the pre cat censor , throttle body , Maff, fuel canister thingy, injectors, coil pack, I am getting lost with what to try next . Any help would be great,

Hi Paul, do you have a topic already for the same problem? I seem to remember reading a closed loop/open loop post recently?

Lexia open loop reading

closed loop

Sorry yes i do, I dont know why I did this one, I think I posted it form my ipad and got lost, Still trying to get an ecu for this car, it has been an abolute nightmare, But I will sort once and for all.
