the dealer recomends getting fuel injectors cleaned at 30'000 miles. what exactly do they do and can it be done yourself.

MattJ

add fuel injector cleaner to your gas tank. id also use a top engine cleaner like sea foam after to remove any gunk accumulated from buildup

is that all they do for 110 bucks. thanks

MattJ

Well when you goto a dealership and do it, they give you a top engine cleaner, and fuel injection service with a high pressure machine. Its better than what you can do at home but you can save yourself 100 bucks and spend the 10 on the products yourself and get some results. I work for a dealership and ive always done everything myself.

It might not be a bad idea to take the injectors off and change your O-rings as well.

You can clean your own fuel system by using a good cleaner,I like Seafoam,and taking the car for a long drive.By long,I mean a couple of hours, the cleaner has to have time to work.The injectors get dirty from too many start-stop cycles.Everytime you shut the car engine down the gas that remains on the injectors dries on there and leaves a varnish deposit.The next time the engine is started this varnish is washed off,if the engine is run long enough.If it's not,you get another layer drying on top of the last deposit and so on.It depends on the amount of detergent in the fuel you buy how fast the old layer is cleaned off.I had to drive my wife's minivan for a week to clean the gom off the injectors and valves so that it wouldn't hesitate in the morning.Thats all I had to do,drive the engine clean,but I drive 50 miles one way to work.

Actually when I took my car to the Ford dealer once to service the fuel system, they were going to take the whole thing apart. They were gonna take off the fuel rails and injectors to be cleaned, then blow the fuel line clean, replace the fuel filter ,clean the fuel tank, and replace the pump and sock. It was going to cost around 700 dollars. Needless to say I didnt pay that so I took the car to a small shop to have the fuel pump put on and I ran a can of Lucas fuel system cleaner through it. I couldnt be happier and I have a bigger pump for the nitrous. It hasnt had any problems since then. I think Ford wanted even more money from me, But I dont have any to give them. :shifty:

Speaking of this, I probably need to replace my fuel filter.

Man this car has gotten more money into it when it sits, than when its out on the road in the better climate.

how does that work?

Gas gunks up and funks up your filter let alone other things...only when its sitting for a period of time thats why you put fresh fuel in and once in awhile

Summit racing used to sell a pressurized fuel injector cleaner that you screwed on to the schrader valve, opened the valve to the can and then turned the motor on. I saw them do it on Shadetree mechanic years ago with great results.... I can't find it on their website (Summit) but they probably still sell it

ok, I don't know what high pressure machine mattj is talking about, but i too have worked at a ford dealer as a mech, and we did use something like what cobra1923 is talking about in conjunction with the tank treatment and intake foam. also we took off the thottle body and cleaned it as well. a company called otc i think, makes a canister that you fill with fuel injector cleaner that will hook up to a air compressor. all you do is shut off your fuel pump and run just the can through untill it stalls.
