does anyone know the best way to clean injectors on my 93 318 magnum?? im thinking to pull all of them out and soak them in a sonic cleaner. will this work?? how much work and cost to rebuild them?? thank you

 

marvel mystery oil. use 4 oz in 10 gal of gas, in the tank. check out "Bob is the oil Guy". the mmo will take a while to work. but its easy to use. been using it for 3 decades.

 

Not that hard to take out but kinda hard to put back in. I would use an injector cleaner in the gas if the plugs are not showing a problem. I had 2 plugs foul constantly so I finally pulled the injectors and the 2 were plugged at the top. Hooked to my battery to open and shot Wd-40 into them and they opened right up after a few shots. Truck works great now.

 

Just a warning. If you are using a battery to open the injectors you can burn out the injectors if the voltage is applied for too long.

 

Aje, I used Fuel Injection Specialties on 11051 Wye Rd. just off Perrin Beital in NE San Antonio. Charged me $45 each injector. ph: 210-654-0774.http://www.fuelinjection.com/ I thought it was pretty to remove them following the procedure in the manual.

 

thanks sixgun,for the leed on the EFI shop. i have no loss of power at all,just sometimes hard starting when sitting over night. fuel pump/sending unit are only about a year old,new filter,and just changed out the pressure regulator.
oh forgot to mention a slight rough idle now and then.
i pulled the spark plugs and they were kind of rich,from excess fuel drip at the injectors. for now i will change the plugs and run something good through the gas tank maybe i can get it to clear itself. thank you

 

I highly recommend a full can of SeaFoam for a full tank of gas for injector cleaning. If your driving is erratic I suggest you use a time when you are using the tank of gas over the longest period of time. This allows the injectors to be exposed to the cleaner longer than say on a trip where you use the full tank in a couple of hours.

 

i had to change my computer(ecu/pcm) cause of another issue.
it starts up and runs 120 % now,so my injection problem was also due to the bad computer.
also the computer showed no trouble codes either.
