Re: 166 Engine warning light.... :eek:
Hunter - let me know how you get on with AlfaTech. I've had both fantastic and awful experiences with them in the past.
For example, they didn't spot the dead MAF, lambda or perished intake hose when I asked them to check the car over when I bought it. They also fitted the wrong air filter. I then took it back to them for the MOT so that I could leave it with them to fix their own mistakes if it failed. It passed, they did a load of odd jobs for nothing, and got it back to me the same day.
If you're not happy with them, it's worth making the trek to Roger at PeakAlfa in Hope - he knows the 166 very very well and is a top bloke.
As for your MAF, I have an earlier engine than you (so a different warning light) but had similar problems. Car revved and went fine, but was quite thirsty. To give you an idea, when I got it it averaged 24 mpg. Now it's over 30.
156 2.4jtd working it's way towards perfect condition. Loving the diesel warpage!
