Hi, i have a question: Does Lexus es300, 1992 has a carburetor? and can i use carb and injector cleaner, cause it might damage something?
But what I really wanted to know, does anybody know how to clean injectors off the car? and does it worth that?
Oh ya one more question, whats the deal with fuel filter? I mean if I change it and put some stp injecter cleaner in tank, it gonna give me same result as off car cleaning?\
thanks!!!!Off car injector cleaning Lexus ES300, 92?
Carburetors have not been used since the mid to late 80's.
Off the car cleaning by a professional usually involves immersing the injector in a solvent and cleaning it in an ultrasonic washer.
An in the tank treatment will not have nearly the effect of an off the car cleaning.
I don't think off the car cleaning is really that worthwhile unless you know the injector is clogged. For a home mechanic, there's no good, safe way to tell. If you want to save some money, you might be able to find a shop that will check the injectors out and clean them for you if your take them off and bring them in.
