Hi all -
Back in the Alfa fold at the moment with a 156 2.0 JTS, which displays the above fault codes. They all clear when told, but have all come back yesterday after probably 20 miles.
The car doesn't run too badly, but can be awkward picking up off idle, which seems to be slightly stumbly as well. Can't really say as regards performance, as I have not driven another one, but it subjectively feels OK - possibly a little flat, as throttle response feels a little sluggish, but I might just be reacting to the MIL being on!
If I'm doing my research correctly, then they (in order) probably Brake light switch (No cruise!) and a dodgy Lambda sensor, but the latter two have me a little confused, but may point to MAF failure?
Am I on the right track from your collective experience, or barking up the wrong tree?
