Rookie, Yes they can, your favorite repair shop or GM dealer should have the equipment to flush the injectors. If the injectors have never been cleaned, it is a good idea.
Also, if you know you have gotten some contaminated fuel, replace the fuel filter.
Good luck and let me know.
Regards,

THE 91 NISSAN STANZA idlesreal good but when you press the gas it goes fast then slow then fast and slow again will not run smooth


could be clogged fuel injectors, fuel pump, fuel filter first what I would do is clean fuel injectors and replace fuel filter, if there is no codes, meaning your check engine light is not on, some times bad gas can do this or water in gas, better to try the easy things first, plus they real dont cost.much, now I use Lucas fuel injector cleaner myself, I have always got good response from it, plus if need to, you can put a tube in every day, thats if you use about 10 gallons of gas everyday so.try this first, cost for Lucas is around $6 also change fuel filter, cost any where from $7 to $25

First I need to know year make and model.
My guess is the pump is faulty. But you would need to find out if it is getting power. And you said you checked the fuses.
On most cars there is a relay that may be in the circuit before the fuse.

The fuel injectors have a resistance of between 10 to 18 ohms.Test each injector. If any of the injector readings are higher or lower than they should be, you need to replace them.
For more troubleshooting:---

Put a long screwdriver directly on the injector while the car is running. Hold the handle up to your ear. You should be able to hear a rhythmic clicking sound. If you do, your injector is good. Hearing a clunk-clunk type noise means you have found your problem. Hearing silence or unusual clicking patterns means either the injector, wires or plunger may be bad or sticking. You will either have to clean or replace them.

-------------

Many a times you get black smoke from exhaust due to faulty injectors.Check fuel injectors. Leaking injectors create an overly rich air/fuel mixture and cause black smoke. Take the valve cover off and look at the exhaust part of the injector, when it is running. Each time the injector fires, you should see oil exhausting from it. If you see oil coming out, then the injector is good. When replacing a bad injector, take the glow plug out and crank the engine to get any oil out of the cylinder.----------------- This should help.Thank you.

My 1999 cadillac deville ran out of gas i put gas back in it but it just turn over it want start can somebody tell me why


How much gas did you put in? You should put in at least 3 gallons, and turn on the ignition switch, but don't turn it to start, let it sit for about 20 seconds to 'prime' the injectors/lines. Try to start it then. If you still cannot get it to start, check the injector rails for gas, there is what looks like a tire valve on top of the engine with a light green, plastic cap.Turn the key on and, with a rag thrown over the valve push in the pin in the center-you should get a healthy stream of gas out of it (use the rag to protect yourself from the spray. No spray? Either a clogged fuel filter, bad fuel regulator, the 'sock' filter in the tank is clogged, or the fuel pump is history. Running a tank low or out of fuel is real bad, because the fuel acts to cool a fuel pump. If it overheated badly while empty, you might have cooked it.

I have a 1999 Tahoe and it has p0171 code, I tried cleaning the MAF and put some injector additive in my gas to clean everything up but the code came back. Where do I go from here?


You have an O2 Sensor code on bank 1
It may be bad and it may not

Injector Cleaner is a waste of money
Do you really think 10oz in a 20 gallon fuel tank
would do anything? Have you ever seen it recommended
in the owners manual
You go to the auto parts store, for parts,nothing else there
your vehicle needs.

Check Lights have been Govt Mandated, and on vehicles for 30 years,
so why did you not check for the PO171 code,look it up and find out
why the sensor went out of range.
Look for vacuum leaks,(a lean condition)
Have a scanner put on veh and look at O2 Data

The car shakes back and forth and has about one half of the power it used to have, it seems one of the cylinders isnt working


SOUNDS LIKE IT NEEDS A MAJOR TUNE UP, PLUGS,PLUG WIRES ,CAP,ROTOR BUTTON, FUEL FILTER,AND A FULL FUEL SYSTEM CLEANING,BUT IT SOUNDS LIKE MOST OF YOUR PROBLEM IS THE PLUGS & WIRES, IF THAT DOES THE TRICK ,I WOULD REPLACE THE FUEL FILTER,AND PUT SOME REALLY GOOD FUEL SYSTEM CLEANER IN IT TO HELP CLEAN THE FUEL INJECTORS, & SYSTEM, BECAUSE IF PLUGS & WIRES DON'T FIX IT ,IT COULD ALSO BE A BAD,OR CLOGGED FUEL INJECTOR,AND ANOTHER BUT LESS LIKELY CAUSE FOR A MISS ,OR A DEAD CYLINDER IS A BURNT OR BAD VALVE,OR IT COULD HAVE JUMPED TIME ,DUE TO NOT REPLACING THE TIMING BELT ON IT'S SCHEDULED TIME.

1999 Ford Taurus mechanical problem


Hello,
your problem appears to be the idle control motor located on the air intake manifold it is a small motor that goes bad quite often. Other items that can cause this is a bad /clogged air filter or a tune up (spark plugs and wires), or clogged fuel injectors. to clean the injectors you can buy a container of fuel system cleaner and pour it into the gas tank and as you drive it cleans the system.

Once the fuel system is cleaned via a tankful of cleaner & gas then the idle controller motor would be next on the list to be replaced.

Good Luck !
