Fuel injector problem

875spdpny · 08-30-2009

I think my fuel injectors might be clogged since my car wont go over 2500 rpm. How do u clean them or if you cant replace them?

If they're truly clogged, they must come completely OFF the car and taken to a shop for proper cleaning. Running a bottle of injector cleaner through the tank will NOT get the job done. That's like throwing a bottle on water on a house fire.

There are some garages, that are able to do a proper cleaning without taken them out. Call around it's a three stage process, the chemicals I think are from 3M and it works well. They do a complete fuel system cleaning, in a three stage process without removing your injectors, Mike. SCT Tuner.

P.S. I had my wife's car done, she does a lot of city driving. And you should have seen, the sh*t that came out of her exhaust, Mike.

Id say you have another problem then clogged inj. Why would they all clog? Check your fuel pressure at the schrader valve, check the conn on your MAF and you may consider changing your fuel reg.

Never heard of such a thing.

Places like Precision Tune does the cleaning with the injectors on the car and it takes about an hour of your engine idling while their cleaning solution runs through the engine.

Sweet! Does this sound like clogged injectors. 2500 rpms is not much and it should be different w/ and w/ out a load. (neutral-drive)

alrite cool..well i dont have a MAFS because i have an 87 5.0 and they have speed density instead.

I would have said it may have had something to do with the mass air but he dont have one so....... I would agree with the above statement. You need to check fuel pressure and see if its increasing along with engine demand.
