    Engine finally works just fine! After an excessive maintenance work and preventing replacement of many sensors and parts, I had an intermittent CEL 1-4 with , huge fuel consumption and crazy HC, shooted plugs in 1-4 which led me to discover a heavily leaking FPR in 1-4 from the vacuum side. After FPR replacement the engine tranformed. Below you can see the current analysis. Just I would like to ask if the O2 value is normal or indicate some lack of air supply. The air filter is new.

    FPR leaking into a vacuum line is an excellent find and a sneaky way to have an over rich condition. Nice job.

    Later today I will upload a photo from the new FPRs (I replaced both) as I relocate them due to confined space. I used adjustable FPRs bu PROTOXIDE especialy designed for 348 / Mondial T with the correct dia./pitch of pipes' threads.
