I was doing a spot of trouble shooting on my alfa 156 V6 (1999 model) today and wanted to see if I could get to the bottom of a couple of problems that have been getting worse over the months.
There are two issues here but I thought they may be connected:
1) When I turn the car on from cold I notice that the engine sounds unusually noisy, on closer inspection when I pop the bonnet it seems to be coming from the area surrounding the cam belt. I filmed in on my iphone below (you can hear the noise to some degree). Also when left alone the noise gets loader and quieter you'll see about 20-30 seconds in it does this.
2) The car has an intermittent (getting worse) idling 'cut out' issue. When idling (often at a red light) the car will after say 30 seconds of sitting the injection warning light comes on and the engine splutters and goes into 'slow' mode where it becomes very hard to drive (it will drive, just very slow and odd performance). To fix this issue I have to turn the engine off, and turn it back on again, normally this fixes the issue suggesting that it's a sensor/electrics issues perhaps. My start was going to be checking out any sensors that determine air/gas intake when the car idles as it seems this may be knackered or not set properly. Any tips on this are welcome too, thought I would mentioned since it may be connected to the load engine noise issue also perhaps.
The cambelt is fairly overdue a change (its been about 120k miles now since the last change which I know is pretty bad, just saving up to get this done since in Sweden where I live it costs a bomb!). I was hoping to diagnose what the load noise was though as wouldnt think this would just be an old timing belt?
