Injector Cleaning - Anyone Had It Done?

[Guest fredster]

Hi Folks,

 

 

Thinking of having this done. My 1.9 runs pretty well but has crappy idle and smells of petrol a bit when driving with the window open. Before I bought it it had sat on a driveway for a year or two unused so I'm thinking there's probably deposits etc in fuel system. Just wondered if you people had views on this. Changed fuel filter and gave it good service before starting her up after I bought her.

 

cheers

Very unlikely to be the injectors, plus the only way I know of cleaning them is ultrasonic cleaning which seems to be more likely to destroy them than fix anything.

Try looking up ECU temperature sensor as a duff one of these (or the wiring to it) will cause your problems

Will be a waste of around £100 as it won't sort the smell of fuel. I had mine done as I thought one of them was weeping as teh plug seemed pretty wet when i removed. The test report said that they were all spot on and no problems with them.

Agreed it woun't be the injecotrs, although I don't agree about cleaning being a bad idea - just not useful in your case.

 

Clean out the AFM, get the ignition timing set-up right (run car on 98+ octane fuel and then set-up), adjust the idle mixture (allen key on the AFM).

P.S. From my experience cleaned injectors (ultrasonically that is) give a bit more go at high revs but make no difference at idle. I've had two sets done on different cars.

I only started to notice the smell of fuel after doing a fuel filter change. Could it be that you have overtightened the connections and actually created a leak, where before there was none. I only ask this as it appears this is what I managed to do, but may resort to good old PTFE tape to repair the problem...if it's good enough for NASA...

 

 

 

 

...then it's bound to burst into flames!

I can clean injectors with an ultra sonic bath but to be honest, on your type of injector the results aren't brilliant. There is another machine by ASNEW which is slightly better but to be honest, this generation of injector isnt that fussy about being spotless.

I noticed a big improvement after having mine cleaned.

They post them back within 2 days and only cost about £30 IIRC.

They give you a report of the results before & after cleaning. replace the pintle caps & filters and fit new seals.

Money well spent if you ask me!

 

edit Just looked its gone up to £45.

Still worth it though IMO.
