Re: problem with my alfa

what does "doped rev" mean? i guess you mean the revs drop when you brake? that is usually due to a dirty throttle body. clean the butterfly valve, especially where it meets the throttle body, and also reset the ecu (disconnect battery for an hour)

Re: problem with my alfa

Don't touch your throttle body!!!!!

It's a fly-by-wire type and it's a common problem for them to go faulty when you clean them, this will leave you with a car thats nearly un-driveable. Happened to mine.

My car has the problem yours has but it's not bad enough to cut out, the rev's just dip.

I found out it doesn't just happen when braking, if I let the car roll to a stop, when the rev's drop to idle, they then start slowly going down and back up for as long as the car is still moving. Not sure of the cause though. It's not a big problem for me, would be annoying if it got to the point it cuts out like yours does though.

Re: problem with my alfa

I don't think cars of that age are fly by wire?
