How to clean injectors?

f00g00 · 06-22-2006, 05:49 AM

Well scince you went to all that trouble.
I did it with them removed by getting some carb cleaner and put a little tape aroung the straw that came with the carb cleaner so when installed in the fuel inlet it had a good fit. The you need to open the injector so I had an injector plug from an old harness, hooked the wires to 12 volts and sprayed till the pattern was good once the injector was open.
A little advice though is wear some goggles or something to protect your eyes from getting flying debri or cleaner in them.
Now I use the method mrnickleye talked about here.

there are places that will professionally clean and balance fuel injectors . i think for around $25 per injector

im not sure but i believe 12 volts is to much voltage on the injectors

yeah I would think that 12v would damage something

Correct voltage is around 1.5V to 3V... Using a single AA Battery works great.

Will It hurt the injector if you connect it backwards, I wouldn't think so, I think It just wouldn't open the injector.

I'm not sure if it hurts it... When I did that to test my injectors, they just didn't open when the polarity was reversed. I haven't had any problems with them since I've checked them out, so I don't think it hurts them, but I wouldn't do it if at all possible (just in case it does).
