PS. I'll also give it another clean :-)
Matt, I have put a K&N filter on, the method I used was to keep the pipe from the throttle body, to this attach a ally adapter 70mm to 70mm, then the rubber flexible pipe that joins the air mass sensor to the existing filter housing, use this to join the ally adaptor to the air mass sensor, then the K&N goes directly onto the opposite end of the air mass sensor. the space is very tight, I have also put an air feed in to cool things down.
FYI K&N part number RC 4540 ally adaptor SHJ 70 both from Demon Tweeks.

Please see below I will be replacing the pipe work with chrome and red silicon joints at some point.

Re: Barchetta Hunting on idle

I had this problem too, tried cleaning the idle control valve, throttle body - no difference. Fitted a new idle control valve - no difference. So decided to live with it. Then the battery died - so fitted a new one, and guess what - the car now runs perfect!!!!! It appears that the idle control valve is voltage dependant so check your battery and connections.

Yes, indeed, hadn't thought of that!

Thanks,

Had to drive through a flood to get home tonight (live in Berkshire) - bumped up onto the pavement and kept the revv's high but a little worried what I will be getting up to tomorrow morning - kinda will it/won't it in terms of electrics.........

Thankfully Binfield is on the top of a hill so the village is OK - trouble is the water ran off Binfield in all directions and collected at the bottom of the hill - hence my wading expedition on the way home!!

Work car park flooded to about 2ft deep, 30ft wide and about 100ft along - I had to laugh at the sales guy in his Prada shoes wading to his SLK.........

Was it from a fully charged new battery or from the recet of the ECU?

My battery is not at her best condition (when i start the engine the cd player stops working and the antenna starts to move inside) but i dont have problems at idling,i know i am lucky !!

Are you actually ROFL'ing Bill?

Sounds unhygienic

Re: Barchetta Hunting on idle

Well, I have:

* Changed the battery (new one is slightly smaller so a bit more room to work).
* Changed the plugs (got NGK ones).

I then drove to the Schloss Dyke car show (great day out) and it ran better and seemed more responsive but still not quite right at low revs.

So, next I:

* Cleaned the throttle body again.
* Tapped out quite a lot of dedbris from the CDA.
* Re-arranged the air intake assembly so the mass air sensor is directly after the throttle body and the breather pipe is no longer directed into the air intake system. I had to do a little work with the battery to make room.

I took her for a spin and it seems better, but doesn't idle evenly for about 20 seconds, then settles down. I had the battery out overnight so it might fix itself as the computer adjusts. On the other hand the revs don't drop when coming to a quick halt and she seemed to go well on the motorway.

If it sorts itself out and runs well for a week or so, I'll order the breather catch tank like Doc.

Cheers,

Matt.
