Hi everyone
I have alfa v6 which sometimes shows eobd light on dash. i used multiecuscan and read p0300,p0301,p0302,p303 codes. so i changed two lambdas on that bank.
fault still shows after reset and clear of ecu. car is well serviced with new plugs, no air leaks and apart from dash light runs perfectly. any ideas? :?:
