  1. 1.9 JTDm injection correction values

    Alfa 159, Brera & 946 Spider
    What do people think of as within the normal range? At idle and at 2000 rpm mine fluctuate about a bit but 2 and 4 seem to be below 1 most of the time whereas 1 and 3 tend to be closer to 2. These figures are under no load conditions measured with MES. Is this considered within the normal range?

    Back in 2001 when I bought my 147 1.6ts,it had a problem. There was a knock in the engine between 2000-2300 rpm (at this point I started wondering what a 'knocking sensor' is used for). The problem you might say wasn't that big, but the thing is that when driving in the city or going up a...

  8. Fuse F-11 Electronic injection sundry secondary services

    Alfa 159, Brera & 946 Spider
    Does anyone know what circuit fuse F-11 supports? I've had this fuse blow with increasing regularity which results in the ECU putting the engine into limp mode. Also accompanying this is the usual gaggle of failure messages on the dash, ASR, hill holder etc. Using AlfaOBD shows up a long list...

    Alfa 147, 156 & GT
    Morning all, Still trying to get to the bottom of the poor starting of the 156 JTD.

Glow plugs and relay are fine, fuel...

    During a 340km round trip out of Sofia today, what the owner's manual identifies as "Avaria del sistema iniezionne" light came on (see pic) after about 60kms of motorway cruising. Google has kindly translated this for me as 'Injection system failure', which I take to refer to the fuel injection...

    Hi, Driving home from my friend's house tonight, I've come across an issue that the previous owner of my 166 told me he'd had in the past but that it hadn't done it for a while before he parked it up for 5 years due to other issues that I've now resolved. The fuel injection system light has...

  20. Direct injection and historical problems

    Alfa Giulia
    Just wondering - not sure anyone will have a good answer for another decade :) The early direct injection engines like the Alfa JTS, but not Alfa alone by any means - RS6 anyone? - have suffered from carbon buildup. That's because there's no washing effect from the fuel. Does anyone know if...
