injectors

can anyone tell me what fuel injectors should be in my A610 and what the flow rate is?

Bosch 804's , 336cc/min

thats what i thought i've been having this rough idiling problem since i got the car so I'm taking the injectors out to get them cleaned and the patterns checked.....i was having a wee look to see whats what and the injectors that are in my car look nothing like the 804's i've got in the garage

Loads of A610's have rough idle problems, more so when the car is slightly warmed up..

It is normally dirty injectors, lamba or fuel pump, as there is only one pump at the front of the car on the A610 (GTA has two pumps) and it has to do a lot of work..

that's exactly what happens with mine first 2 or 3 mins it runs smooth then starts idling rough..tried the add to the tank injector cleaner just to see if it made a difference....it did for about 3 days lol then back to the way it was...so i'm pretty sure its them thats causing the problem.
been quoted £137 for cleaning pattern and flow check for the 6 of them...is that about the norm?
this is the place that i'm taking them too.......they seem to know there stuff http://www.autowerke.ltd.uk/

On friday I received a quote.

Thanks for the e-mail
A set of six comes out at £95 inc vat.
You will get a before and after report sheet when finished

Trouble is, price is not always a guide of quality???

They all use the same method/equipment .

thats a big difference in price.maybe i'll shop around

Yes, on warm up the ecu goes open loop (doesnt rely on lambda signal) and dumps in extra fuel for cold starting and running. The 'extra' fuel is enough for it to run smoothly, and then it starts to miss a beat within a minute or too...

Makes the car feel more laggy and unresponsive too..?, and a misfire if you hold the revs at around 2000....?

erm..yes and yes so if i'm reading this right get injectors cleaned,new fuel filter check fuel pumps ok,check lambda(if thats possible) and all should be well

You might want to buy new ones, they are not expensive for the 610.

Too many company cars for too long !

So, how do I get injectors out. I'm guessing that they are not screw in/out, because they are all installed in the same orientation. Are they just clipped in between the rail and the inlet manifolds, or something. It looks like a 5 minute job to remove 2 bolts and lift the rail to release the clips holding in the injectors.

Being French, I'm sure there is just 1 little point I have not yet sussed??? Any advice from any one?

Its as easy as you describe, 2 bolts per rail, pull and then unclip the injectors. I can change em in about 20minutes!

Thanks peter, sounds too good to be true, I'm bound to hit a snag. thanks again.
