Petrol injectors. A Godsend or a nightmare!

[CTCNetwork]

Hi,

Just a quick note to say that Jim provided an excellent service and turn-a-round for my injectors.

They are now fitted back onto the car. Testing will follow the completion of the matrix!!

Thanks Jim....

After reading this link http://www.volvoforums.org.uk/showthread.php?t=49683 that was posted on another forum i phoned jimathan to get my injectors cheacked and cleaned
Not that i suspected anything wrong with them but for £6 each what can i lose?
When i arrived at jims house i was welcomed and a cup of coffee was soon negotiated
I was then showen to his little enginers work shop "a little boystoy heaven" my injectors where soon set up and tested to see how they where performing
I was totaly shocked as only 2 where doing as they should 1 was passing fuel constantly and the other 2 where acting more like a jet rather then a fine spray
Jim then tested them on idle upto 6000 rpms again on full load 1 wasnt working at all and the other 4 was having some sort of spraying fit
So on to the ultrasonic bath to give them a full beep clean including a reverce clean
Now for a retest what a complete difference all 5 where acting as they should including the one that was passing fuel
I have now refitted the injectors and on start up i have noticed that my car now starts better and reves smother but i havent tacken it for a test drive as half my dash is still not fitted due to a stereo upgrade
Verdict i am realy impressed although i have only seen them working on a bench but from what i have seen i am well pleased with the results
Thanks to Jim for making the time to sort my injectors out
and to his wife for all the coffee

All seems very good Can you do this for a 1999 S80 2.4? TBH im not even sure it has injectors :S how silly do I feel? From what I understand on VADIS it does. Hopefully would make the whole car run better. (Still in need of ETM, alarm siren and SRS control unit and 4 new tyres so not the 1st priority im afraid but something I will want to do - 4 new tyres coming monday )

Yes, you'll have injectors...
But do you know how to remove them??
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..

Ahhh Yes Jim... I have a confession.

In a rather heated discussion on VPCUK about running injectors near their limits I posted a link to your pictures over here to illustrate the dangers of not having enough resreve capacity.....
(BTW, Thanks for posting those pictures they are priceless information)

Then Tony followed it and arrived here....

Now look what's happened.........

Anyway Glad it was of help to you both.

It's got me wondering though, Mine have been on for about 9 months now from new, in that time they have done about 35,000 miles and had a fuel pump and engine change. Do you think it's worthwhile giving them a clean? or should I leave them a little longer?

I'm in Blackburn, so I could whip them out and cycle over to yours if it's worth cleaning them.

You're certainly getting to meet folks with this little scheme, it's a cracking idea!!

Cheers.

Well Jim, you've also opened a few peoples eyes.

I'm just thinking of all the basic so called "stage 0 tuning" were people are recomended to do basic things like plugs, leads, hoses, and filters etc....

But never have I seen injector cleaning on the list. That looks like a big omission, surely before spending hundreds on getting a car tuned one should really have a nice clean set of injectors. Otherwise it's going to compromise the performance, especially on a highly tuned car.

I think all stage 0 tuning guides will now be re-written, Thanks Jim!

Hi Nuisance. Do you know what? I think you just hit the nail on the head. I never thought of it like that but your bang on there. We think nothing of spending £30.00 on plugs, another £50.00 on dizzy caps, rotor arms, oil & filters; so realy it is a bit of a no brainer if you don’t have the injectors checked. If only for peace of mind.

Personally, after having seen the results I would be having them checked at every 20.000 miles. You wouldn’t leave your plugs and filter that long would you?

Thanks guys for all the positive feedback.
Jim
