thread hijack- How are the injectors modified? I uncertainly recall reading about removing the 'nozzle' to the front of it thereby making your 400+cc injectors into 600+ However the results of this varies in cc rating by <20% among the modified injectors. Shocked

i just use bar's throttle body/injector cleaner. 20 dollars, buy 2 if it's extremely dirty

dismantle intake pipe, spray directly into the throttle body/butterfly valve until the can is done

Another Hijack, how often should your injectors be cleaned or serviced?

Anil_Sooknanan · Posted: Sun May 10, 2009 9:37 am Post subject:

it's all about how you find the car performing , but i'll say 6 - 9 months

The tapping methods quite effective ... but make sure and tap quickly as leaving it too long will damage your injector. You must also remove all the o-rings as the carb spray will damage those in the cleaning process.

Steps:

1- Remove injectors
2- Remove all the o-rings from the injectors
3- Locate an old injector jack from a scrap yard to make connecting the pins of the injectors to the battery easier. This will be used in the tapping process.
4. Place all the injectors in a carb spray solution and allow them to soak . The longer they are left, the easier the gunk will dissolve away.
5 Take an injector and attach the scrap yard jack to it.
6. Attach one wire to the -ve pole of the battery and use the other wire for tapping quickly. Get someone to help you do this or if you want to be creative, design a foot activated switching system Exclamation

7 Spray the carb spray through the injector while tapping the wire. You will notice a definite change in spray pattern and you will have a pretty good idea when it is cleaned properly.
8 Repeat from step 5 for the other remaining injectors.

I use Chevron Techron fuel injector cleaner in my car. Then again i run a honda accord but it's proven best, and test states it's the preferred choice for honda's
so if you aren't sure which to use, go with Chevron.

where can i get a line to hook from the can to the injectors???

Anil_Sooknanan · Posted: Fri Oct 02, 2009 10:09 pm Post subject:

what line?for what type of can?

someone had told me injectors operate at around 5-6V and that connecting them directly to a 12V battery is likely to burn them.. is this true?

what do you guys use to connect the injector cleaner (like gum solve) to the injector inlet?

the battery method sounds kinda shaky. aeren't some injectors high impedence and some low?
as stated before, i usually disconnect the fuel line before the fuel filter and let the gas drain off. fill the filter with 'BARS' carb spray and re connect the line then use a small vise-grip to pinch the overflow line to ensure the carb cleaner doesn't get back to the gas tank and fuel pressure is maximised. the car may not idle as it bogs down (too rich) so peddle lightly but the injectors are cleaned easily.

got the green thingamajig on amazon (can tap) $12 US and the cleaners are available at most parts places approx $45

you also need a hose from the tap to your rail but that's a mix and match for your application. an old aircon line, a joiner and some cheap hose & clips from the parts place worked for me.

Already posted in the Mazda section but i'll put here too......

Click for full-size.

That's the "Can Tap" off amazon on the can of pressurised cleaner (which now costs $50 BTW Penray)

Clamp off the return line

Click for full-size.

Attach to fuel rail (follow the blue line) after you've disabled the fuel pump (easier said than done as the fuse disabled both pump AND injectors on the 323 ...fcukers in Japan)

Click for full-size.

Start and let the engine run off the can. At idle you'll get about 6 min (i always run 2 cans).

Remember that if your injectors were not dirty to begin with, its hardly likely you'll see any improvement.

Did this more as preventative maintenance than anything else.

nice advice Dave. Thx. Will try next time.

I usually take the injectors out individually and spray them with the cleaner and give them a lil brush with a toothbrush.

I always heard that cleaning while pulsing it was the best...never tried it...but ur method sounding as the closest option i can try

about injector cleaners...i have always recommended Amsoil as one of the best on the market.....u get 4 uses out of a bottle......1/4 for every use when filling ur tank

about using it every fill up....dat not advisable..because i also heard it damages the lining of the hoses

well i add injector cleaner like every three months...which still might be too often because the amsoil bottle recommends after every 1000-1500 miles of continuous use
