I think one of my injectors is dirty causing LOTS of carbon build up in cylinder 4(nearest dizzy). All other cylinders looked good when I checked the plugs except cylinder 4. I did some research and from what I understand the pros use a ultra sonic bath to free up debris and flush out the injector. At work I have such a machine but I need to know what type of solvent I should use to "bath" the injectors in?

Thanks

 

You Can Use Brake Or Throttle Bodt Cleaner, That What I Used When I Cleaned Mine

 

unless you rig something to pulse the injectors while on the ultrasonic cleaner, its going to do you no good.

 

Use one of those big 12v lattern batteries (not a car battery) and touch the leads with some wire. it will pulse.
