Petrol injectors. A Godsend or a nightmare!

[Engineer]

Nice work it will save people money, however before you all rush off your injectors for testing / cleaning here’s a few thoughts.

1. Injectors have been removed from 100K plus cars when something else has let go and found to be performing as new.
2. New ones tested didn’t.
3. I tested mine at 76K prior to mapping etc. and they were on the button.
4. Fuel quality is important.
5. Injector usage cycles are important (as mentioned with regard to LPG).

They will lie under the fuel rail... That will need to be removed, injectors unplugged and removed... etc..
It would also be worth getting new ring/seals for the injectors..

I realise now it was quite a silly question lol! I kinda know how to do it with some help from vadis :P It says I should drain the petrol through the valve on the right hand side of the fuel rail?! Do I really have to and if so how would I go about doing that? Thanks

Someone will correct me if im wrong but the pressure usually drops off by itself after a short while. After that you only loose an eggcup full

Hi,

I was under the impression (wrongly perhaps) that the rail should maintain a certain amount of pressure.
But yes, you can bleed off fuel through the Schrader valve on the rail...

Do resist the urge to smoke whilst doing this, won't you...

Hi Des, alls well I hope. You are rite, the rail does hold pressure but given that you can’t compress liquid, it’s not much. Just the expansion of the flexi pipes. I think

Evening all. A question has arisen regarding liability in the event that injectors being returned via Royal Mail go missing. As this is a none profit making service I do not want to be held responsible for: nor can I afford to pay the replacement cost of injectors if they should go astray. Because of this all injectors will now be returned by special delivery with extended insurance up to the value of £2500.00 this will also guarantee next day delivery, and the charge for this will be £6.50. Please take this into account when toting up.
Regards Jim

Jiim Thanks for an excellent service. Transaction carried out in the timescale as stated. They are now fitted and tested. Although I thought the car ran OK before it now runs smoother and quieter now. And from Jim's report they really did have to be cleaned. So my advice to anybody is to have them done. The cost of having them done is negligible. You will soon recoup the cost by better mpg.
