Hey all,
Was wondering if anyone has had any experience with these cars. It's a 2litre engine with mechanical fuel injection

, automatic and has a terrible surge at idle, gets worse when hot and is worse in drive. I am a mechanic myself, but I work at a Toyota dealership and don't have anything to do with mechanical injection let alone audis. It has had the idle speed control valve replaced and I've fixed a few air leaks. I realise it's a long shot but if anyone has come across the problem I'd very much appreciate some advice.
Cheers,
Mike.
