need injectors cleaned..

what is the best thing to pour into the gas tank to clean out the injectors so i wont to take the top half of the motor off.. i have a 1989 ranger 2.9

Fuel Injector cleaner?

yeah but whats the best injector cleaner

I've found that Techron works really well. They sell it at just about any parts place I think it comes in a bottle for 12 gallons of fuel, but run it a little more concentrated like in 6 and you'll be alright.

yeah i just got the truck.. and the guy i got it from said that one of the injectors were completely clogged and bulding up pressure and he said that they all needed to be cleaned or replaced, so i was just gonna see if some good fuel system treatment would work, but i didnt know which kind is best for fuel injection..

I did some research on this topic one time, and Techron seems to have the most positive evaluations for any inexpensive over the counter product. It's also possible to have injector cleaning done at a garage. I believe Pep Boys offers such a service.

On the hondas, I pulled off the fuel rail, took each fuel injector filter off the top and blasted it with my air compressor. It didnt look dirty at all but whatever. I was looking at my ford ranger fuel injectors, I cant take them apart. I have a 1993, so, I dont know what to say.

I hear the professionals have a pressure system that they use to inspect the injector spray and the over pressure them to clear the injector out. I dont know I dont have a system like that.
