Ok, then provide prrof of your claims.
I have found that they do work, in my own tests, with cars that I drive and service. Better gas milage, smoother idle....

I agree I like to see those.
If I remember correct BMW was the first, or one of, to come up with a standard to clean Valves as deposits build up. That of course lead into F/I cleaning as tech came along.
1. Yes, I'm a professional with over 20 years of experience, a community college degree in the field, and numerous factory certifications. Also ASE certified, although ASE is basically worthless as far as knowledge goes.
2. Fuel injection has been around longer than you have, for sure. Who cares when exactly the first one in a car was? That is totally irrelevant.....EFI was not the primary fuel delivery system for the majority of cars until the mid-to-late 80's.
3. Jiffy Lube does not to my knowledge advise that injectors be cleaned every oil change....and neither does anyone else.
And if they did, so what? Who in the hell goes to Jiffy Lube for anything other than oil changes and state inspections anyway? Nobody there knows how to hardly fix a sandwich, much less an automobile. I wouldn't let a bunch of teenaged pimple farmers touch my vehicle.
Bottom line, when you can tell me that you've personally flow tested injectors before and after you personally cleaned them HUNDREDS of times, and you've personally seen the improvement....when you've personally worked on a problem vehicle multiple times with either constant contact with a factory engineer or with one actually working on the car with you....THEN you come back and start handing out some advice.
Otherwise, just read the damn thread and learn something.
Probably letting the fuel pump complete its cycle that happens every time you turn the key on. If that does no good, next time try cycling the key from the off position to "run" several times, but not starting it. Let it sit on "run" for a couple of seconds.
If the car starts okay like this, you may have a fuel pump going bad. It's supposed to hold a certain amount of pressure in the lines so it doesn't have to pump fuel all the way from the tank to the engine while you wind the engine over every morning.

This condition would more than likely point out a faulty fuel pressure regulator than a fuel pump. The fuel pump isn't what holds the pressure. The regulator does that. If it only starts hard after sitting for long while I would skip the fuel injector cleaner and put a fuel pressure tester on overnight. If it bleeds off then I would replace the pressure regulator. They aren't usually that expensive. I'm suprised a mechanic wouldn't ask you these kinds of questions forst before recomending fuel injector cleaning. Than again I'm not. Too many of them are just parts changers that don't actually try and troubleshoot what caused the problem.[/quote]
Incorrect in some cases. In most Fords, the fuel pump is what holds the pressure, not the regulator.
I've replaced several hundred for this exact problem, particularly on late 80's to early 90's vehicles.

Then I suppose Ford engineers are dumber than the ones that work for the government, because they have had service bulletins for years that run various cleaners through either the injectors, air intake, or gas tank to clean the fuel system components.
Also, I suppose that flow testing injectors, then cleaning them, then flow testing them again and seeing a vast improvement means they also don't work, right?
I always like to have the government work on my car. :roll:
make sure you get the "techron/complete" and not the progaurd. The techron complete is much stronger than the progaurd.

I used some injector cleaner on my car (80k miles since last cleaning) and it worked like a charm. I didn't hvae more power, but I had better throttle response.
Kinda OT to this thread..
but can fuel injectors become "noisy"? I can hear ticking noise coming from them. While the car still performs the same, it makes an irritating ticking noise at idle. I've been told that its the fuel injector.
Would cleaning them with some of the products mentioned in this thread remove that noise?

injectors make ticking noises. its just the way they are built (micro electric solenoids). some manufacturers tick more than others. cleaning may help, and certainly doesn't hurt as long as you don't do it too much.
Chevron Techron always does the trick on my mom's Volvo, which has problems with clogged injectors. if you just buy chevron gas from now on, you can save yourself the trouble further down the road, as it has a little bit of techron already in it.
feed it cheap gas and it quickly suffers from problems just like your car.
