Injector Cleaning - Lubemobile?

[ian]

OK, I know I'm going to get laughed at.. :-)

I've had a noticeable fall in fuel economy recently - so I replaced the air filter, cleaned the spark plugs, checked the fuel lines, replaced the fuel filter (all things that needed doing) - no change.

So the next obvious thing (after cleaning the AFM which I'll do next weekend) is to clean the fuel injectors.

But I don't want to take them out myself, so I did a search for a place in Melbourne that would...

I was surprised that lubemobile came up near the top of the google search - and they say they clean them 'in place' ie http://www.lubemobile.com.au/Content_Commo...ter-Service.seo

Has anybody used this and can tell me if it is OK? They specifically list skylines on their web site, but I'm a bit nervous.. Alternatively, can someone recommended an inner city (if possible) Melbourne workshop who would do them for a reasonable price?

Just empty your fuel tanks to about 1/4 then goto auto barn or super cheap autos and buy a bottle of "Fuel Injector Cleaner".

Tip it in and then fill you tank up full.

Drive the car and run it through.

Should be good.

Those products are basically maintenance items - they cannot remove the waxy products that build up on the injector and disrupt the spray pattern.

It is best to get the injectors cleaned external to the engine, because you can then have them checked for correct spray pattern. Cleaning them in-situ "hopes" that the job gets done properly.

If you look in the Yellow Pages (on-line or on paper), under Fuel Injection, there will be various businesses, including mobile services, listed. Find which one does flow testing and spray pattern testing.

Splintex did a good job last time I had a mobile unit clean the injectors.

Hi guys, thanks for the suggestions.

(OO)SKYLINE(OO) - I've already tried the fuel injector cleaner in the petrol - definitely improved it a bit, but not enough...

With flowrite and splintex - I can find both in the phone book, but neither have a web site, and neither have ever been mentioned on SAU (till this thread) so I'm a bit nervous... Do they both do them in place, or remove and clean them?

blind_elk - do you have any specific suggestions of a place to go to, as I'm a bit reluctant to randomly pick one from the yellow pages.. :-)

Splintex will come to you. He does it "out of the car".

If you want to go somewhere, Speed Technology in Mitcham - also "out of car" cleaning.

I did go with the lubemobile - they have a guy who is a skyline enthusiast (Theo) who was very good.

What they do is turn off the fuel pump, take off the fuel line at the engine, and then put their mixture into the engine and let it run for about 20 minutes.

You could smell the stuff coming out of the exhaust.

I haven't managed to go for a long drive yet, but the car did seem to go up a big local hill better..

Even better, while doing this he noticed what might be my fuel problem - my clutch fan is gone (see http://www.skylinesaustralia.com/forums/Sp...F-t263596.html).

So all up I was very impressed.

Cool!

So how did you go?

Is the fuel economy a lot better now?

Let us know.

I've still got one problem to sort out (http://www.skylinesaustralia.com/forums/Spare-R34-Gtt-Cluch-F-t263596.html) then I'll put numbers up.

But in the small amount of driving I've done so far, the engine is running noticeably smoother.

Ah yeah... LOL! Missed that.

Hope it gets fixed.

Smoother is good, so your fuel is obviously flowing to the engine a lot better.

Cool!
