Hi all, thank you in advance for any help I receive.
Long story short - I've just bought my first Alfa - a 2002 156 Sportwagon 2.4, it was a barn find (ish) by a friend of mine - it had been sat for 14months, it's recently had a fluid change and a new alternator - it's fairly clean and rust free and the interior is in mint condition with tan leather and the Bose upgrade. It has good service history has been looked after during its 120k mile life.
When I bought it I knew about the intermittent fault and thought it would be straight forward after reading a few threads on what sounded like the same thing.
So I've had it plugged in with Graham Eddy in Penzance and it came back as an over boost error.
On reading it could be a number of things.....I'm just looking for some advise really.
So this is what's happening......
On start up, drives beautifully - pulls very well and spools well - if I don't drive over 3000 revs it can stay trouble free for up to 10 miles or so if I do boot it usually in 3rd around 3000rpm I'll get the engine management light come on and power will die, if I change into 4th at this point and whilst clutch is pressed leave it long enough that the revs come down to 2500 ish the light will go off again and it'll carry on pulling but not what feels like 100% - this whole thing is more apparent if I'm going up hill??
Apparently previous owner checked hoses and I have personally done MAF sensor clean and EGR clean
I have read about turbo viens and MAP sensor and not got to these yet.
Can anyone out there help me with some knowledge they might have??
Anyone else experienced the same and fixed it?
Let me know if you need more details - I really want to sort it out so I can enjoy my first Alfa to its fullest.
