You may need to update the injectors. There was a TSB advising to upgrade to 4 hole injectors and or fuel rails.

Very broad question, but maybe a tune-up, if needed. Fuel injector cleaner does not give more power. Use proper octane fuel rated for your car. If it requires more than just regular 87 octane, then you might restore a little lost power by using proper octane fuel.

Car will start sometimes other times i will have to continue to crank the engine it cranks everytime


As it cranks, is there white or black exhaust smoke ?? If yes, the fuel injectors have solid build up on the tips. Normally, a quart bottle of injector cleaner treats 20 gallons. Pour 5 to 7 quarts of fuel injector cleaner. With cold engine (been parked for at least an hour or overnight), while cranking engine, have 2nd person spray starting fluid into air filter. DO NOT PRESS ON GAS PEDAL !!! Let the starting fluid do its job of starting the car. Starting fluid is highly combustible, so its important you don't give any gas while its cranking and 2nd person is spraying into air filter. When engine starts, stop spraying starting fluid and give a little gas. If engine begins to die, immediately spray a little starting fluid again. When engine begins to run, let it run a few minutes to let fuel injector cleaner to do its job (loosen solid carbon build up on tips of fuel injectors).

Every thing has been checked - new plugs, sensor, pump, injectors all working fine - but the car turns over just won't fire - Could bad gas cause this? - Car was running fine turned off at work came out 8...


I would suspect water in the gas, as the injection treatment wouldn't affect it like this. Take a sample of the gas from the test port on the fuel rail that's on the intake manifold. You should be able to see if there's water in the gas.

Location of fuel filter on a 2001 audi tt quattro


On a 2001 Audi TT Quattro the fuel filter is located forward of the fuel tank, in the right rear wheel well area. The fuel line clamps are a bit tricky. The change will improve performance. The owners manual does not even list changing the filter. But do it! use a Fram, and it fit perfectly. Good luck.

Runs good when on the gas but wont idle


Dear 24scott,

This sounds like it may be as simple as cleaning the water or gunk out of the gas tank which is what I always do 1st because it's easy and inexpensive.

If your fuel is contaminated with gunk, grime, water and/or bottom junk like rust this will cause stalling!

It's most likely bad fuel or clogged injectors so....
Fill the tank with High Test, Add some dry gas and a good fuel system cleaner or 2 or 3 and this should dissolve all the gunk and clean the injectors!
Read & follow the cans' instruction carefully.

If this cures the problem never let your gas tank get below 1/4 and especially never run it to empty as this is when the gunk and/or water will enter the system!
This Should FixYa!

1999 Taurus has been sitting 4 years, bad gas clogged fuel filter


1.) Change the fuel filter.
2.) remove all old gas (should actually drop the tank)
3.) run injector cleaner get kit to do this from fuel rail as this is probably cover in gunk


You may also have a screen or filter in the gas tank itself that can get clogged. Get rid of as much bad gas as possible. Like I said above it is recommended that you drop your gas tank but if you don't want to make sure to get all old gas out of tank and at the very least put a good amount of stabil in the tank fill with gas do the fuel rail injector cleaner they sell these kits at auto part stores. Hope for the best.

Let me know how it goes.
