    I've recently serviced my car, I changed air/oil/fuel filter, spark plugs and coils. I kinda hoped that this would get rid of this fault code which usually pops up, unfortunately not. After doing about 50 miles today I thought all was well then a short while later the engine light illuminated on...

    Received this code today. After looking at INPA. This has occurred three times. I was thinking of inspecting my crankcase vent valves to see if there are any tears before I consider replacing them. Seems an easy job and not expensive. Anyone else had this code. Every now and then I get a rough...

    Since getting my LPG conversion done I've chalked up about 2000 miles and in that time the MIL light has come on 3 times. I've used INPA to check and on each time it says: "Lambda control tolerance Bank 2: Deviation rich, Sporadic Error" - @2496rpm "Lambda control tolerance Bank 1: Deviation...
