Are you referring to throttle-body injector, or individual port injector systems, or both?

With older carburated vehicles I have removed carbon deposits by fully heating engine to normal,remove air cleaner,hold RPMs to about 3500 min. then slowly pour tap water from a mustard squeeze bottle into both carburator venturas,easing up not to stall the engine,rev it it up a few times,repeat,one pint of liquid or less.

Slowly means slowly,don't drown out the engine,never tried it on later EFI types. The steam produced and impact of the dense liquid molecules,blast loose carbon on valves/pistons,some ports out the exhaust.

So I took the STP product back to the warehouse store.

Since I bought it with a $2.50 coupon, and they refunded me the full price, I made a little profit!

There's no reason to buy a special aftermarket fuel injector cleaner. Use a Top Tier fuel and there won't be a problem to begin with.

I don't think I've ever used an additive to clean the fuel injectors, or if I did I didn't think it would do anything.

I've used additives to condition the fuel, but not to clean the injectors. I don't understand how adding a few ounces of an additive can clean a dirty injector. I've seen dirty valves and it would take a chisel to clean it.

no there is no need to do anything unless your having a problem

first problems should be around 200,000 miles , sooner in a hot climate , then you will need new ones , cleaning will not help

"The MAF has a cleaning cycle which runs automatically every time you shut down the engine."

It apparently needs a little help about once a year. And with 221K miles on the clock, I'm not complaining.

I'm more concerned with keeping my MAF sensor clean. Helps some with mileage and a lot with spark knock. I think I do have a slightly faulty injector which I need to replace.

Nah, I don't bother with it. Never once cleaned an injector. Never had one act up either. Current car - 198,000 miles. Last car - 150,000. Injectors untouched. Looks like cleaners are snake oil.

Sorry 13Octane, didn't mean to offend you. I could have worded it better, I suppose; I'm as annoyed at flaming as you and most people are.

But there is a fair bit of posting on the subject, and some exploring may give you the info you're looking for.

I use Lucas about every oil change but if notice a rough idle or any other fuel performance problems then I will run some BG products 44k cleaner it is kinda price and only available to mechanics and parts stores but worth every penny. If you run a 5 gas analyzer before and after you will see a real difference.

13Octane, there'as been a lot of discussion already on this subject in several threads. You should review thread headings and see what's out there before starting a new one. Then people just jump in and and repeat their previous postings. (Especially annoying on controversial and political theads).)

Here's one which should give you something to start with:

Fuel Additives thread.
