Beck-Arnley makes a fuel injection tune-up kit for the ve and vg. Part# for ve=153-0155 (around $60), and vg=153-0148 (around $120). Why the vg is so much more has got me, I guess there are more gaskets.
But anyway I highly reccomend these kits b/c they include all gaskets and all o-rings and seals for the injectors. The cost from the dealer would be at least three times as much for the parts the kit includes.
The only thing they did not include were the pintle caps, which I also reccomend to be replaced b/c as they get old they can crack and fall into the cylinder. I got lucky there is actually a store one town over from me that carries them and also does injector cleaning (ultra sound bath ~$20 a piece). I did not opt for that b/c I was able to do a very good job of cleaning the filter screens on my own.
I found that the #5 cylinder was leaking through the lower o-ring the most and at least two others were also. The job all together was very straight forward. The only trouble was getting the injectors out of the fuel rail. There must be a fuel injector extractor tool out there somewhere. I pulled them out by placing the head of the injector in the vise (using the jagged teeth on the vise) only applying a little pressure. No damage was done to the injector. with the injector in the vise you can then rotate the injector in the rail and pull at the same time. Installing was accomplished using the same method reversed. Just remmember to clean the old o-ring residue off the injector and fuel rail. If you dont do this the old crud can cut the new o-rings during installation. I used acetone and a q-tip to clean the fuel rail and injector residue. To clean the filter screens I used a cup with alcohol (mineral spirits) and a paint brush (you should have seen how dirty the alcohol was after cleaning all the injectors. Keeping the filter screens clean will allow maximum fuel flow during WOT. And I must say I saw a very pleasing difference in power after doing the job. I'm hoping to see an increase in MPG, as this was the main purpose of this job for me, but the increase in power was more than welcome.
The next time I do this job (in another 70-80k), I'll probably be replacing the injectors. I've read that they typically last about 150k, although what I have just done will have definitley increased there life.

I would say that the filter screens on the injectors were about 30% plugged before cleaning.

 

i wish i had your ballz..... eww.. that did not sound right.. LOL

 

Did you use the FSM for job or was the Haynes/Chilton adequate?

 

I have the fsm, but it really does not go indepth with the procedure.
There are quite a few screws that need to be removed to get the intake plenum off.

When you need to get the fuel rails out, simply cut the fuel hoses with a razor, but note down the length of the hoses so that you can cut exact replacements. for the VE all fuel hoses are 5/16 (make sure you only use fuel injection hose) regular fuel hose cannot withstand the pressure.

I can also report that after doing this job that the engine idles smoother (no more buh buh from the exhaust) and now the tail pipe stays free of carbon build up.

 

just out of curiosity, why didn't you just replace all the injectors. arent you pretty close to 150k? is it alot more expensive to replace them. i was thinking about doing the samew thing since i have 140k on my '92 se and it feels like it needs it.
by the way, thanks for the informative post

 

Actually I have not yet hit 90k
I bought my max 2.5 years ago with 50k on it.
Heck yeah its a lot more to replace all of them. It's like $100 per injector, new of course, I see no point in buying remanufactured. Even if you buy the injectors new, you would stil have to replace all the seals and gaskets.
I think the procedure I did ensured to significantly extend the life of them. They dont leak due to the new seals, and since the filter screens are now clean they will pulse close to the same amount of gas, also the clean screans will prevent a clog that will make the injector over heat and burn the solenoid winding.

If you have 150k on them and they have a resistance that comes close to one another, there is a good chance you can get away with reusing them. So long as you clean all the crap off the filter screens on the injectors and fuel rails and use the gasket kit that beck/arnley sells.

 

wow, thanks i didnt realize it was that much more. im going to get that kit

 

I have been thinking of doing this, but as most others, I was too afraid to dive in... but after reading this post I feel a bit reassured. I am tired of the "buh buh" exhaust noise, and I feel like my injectors are somewhat in need of work. Where can the kit be purchased?

 

you might have to call around.
