boost problem Ford focus st 225
i have some issues with my 2010 focus st.
The biggest problem is the car boosting to only halfway, (0.3 bar ish) however this is not the only problem i have.
the other problem is the car not starting quick and idling roughly. but when the car is running for about 20 seconds it seems to idle fine, and it doesnt matter if the engine is hot or cold..
Other things that showed up were the esp and engine warning light going on and sometimes the engine is sputtering at around 3000rpm when under full load.
i went to a dealer a couple of times but they couldnt find the issue, the fault code it showed was p2178 ( too rich bank1) before that they already replaced the injectors because they were leaking and said maf and map sensor were showing good values.
i have replaced the maf and map sensor and did a kam reset afterwards. i also checked spark plugs and all hoses from the turbo.
a kam reset makes the boost go full again for about 1 or 2 days before it goes back to halfway again.
all help is appreciated!
