Technical Barchetta Hunting on idle

Congratulations! Mine's at the garage today to get the oil leak done. I've also been in touch with BMC and think I can see a better way of mounting the CDA. I'll let you know how it all works out.
 
Well, the garage replaced the plastic piece which sticks out of the top of the engine and has two pipes attached (one goes to the air intake for breathing and the other seems to recycle the oil).

Apparently the piece was cracked and once the engine was hot it was leaking oil. I'm not sure why that should impact the way the engine runs, but I took note of the comments above.

So, today it seems to be running much better, I've noticed that the engine doesn't brake as much as it used too and that it runs more smoothly in traffic jams.

Unfortunatly, it was miss-firing a bit this morning too. However, I think this is the after-effects of the steam clean it was given.

I'll give it a few more days and let you know.

Thanks to all those who've given their ideas on this,

Matt.
 
Well... mine went in yesterday for the variator (& they did the cambelt whilst in there) and even though it still needs a new pressure sensor (next week sometime) it is driving like an absolute dream! I hadn't noticed how noisy and sluggish it had become over time and now it's like a new car. I can actually hear the exhaust note over the engine and I'm well happy :cool: (especially as Fiat picked up the tab)
 
Well it's been a few weeks now and some of the symptoms have started to come back.

I think number one spark plug has a tendency to accumulate moisture around the top of the plug. Neither I nor the garage can see how, but I'm going to have a look again this weekend.

I've also got to buy an 8mm spanner as someone "borrowed" mine :)
 
Ive got a CDA and I'm wondering if anyone else has found a better way to fit them. I assume you all kept the original piece with the mass air sensor in?

Did anyone remove the breather pipe? If so did you just leave it open or put some kind of filter over it? (I mean the breather which takes air our of the engine and feeds ot back into the air intake).

Cheers,

Matt.

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 (y) I will be replacing the pipe work with chrome and red silicon joints at some point.

I am just about to do the same - courtesy of Dr O's old Green kit!! - can't wait for the throaty throttle noise :)
 
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.
 
Italian cars and their batteries! Just put a new one in my Alfa to fix the sat nav/esp failure issues and presto, good as new!

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 my house in Berkshire is built in a flood defence area!

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.........:D

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

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:D !!

Knock on wood! Quickly!
 
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.
