Hi guys, my brother in law has the 190 alloy tech when he puts in 95ron or higher fuel it registers a check power train error on the dash. We hooked up an odb2 scanner and it is registering a P2190 and P2188. Not sure where we should start looking, any suggestions?

They are just codes for too rich during idle/deceleration bank 1 and 2. Leaking injectors, clogged airfilter, dirty MAF are a couple of starting points...

thanks for that, is it possible this may have been caused by cleaning the MAF?
