I have a 1997 Jeep Cherokee Sport and sometimes when I turn it on, it sputters. After the initial sputtering, it evens out and I start driving...it sputters a little bit more then is good until I turn it off. It depends how long I have it off...sometimes it starts right back up and other times it takes a while to start. If it takes a while to start, it sputters...if it starts within a short amount of time, it usually does not sputter. What could it be?

I think the fuel injectors are "leaking down". The injectors are supposed to hold the pressure from the fuel pump at least over night. When the engine is shut off the injectors won't hold pressure and the fuel leaks into the intake manifold and "floods" the engine with fuel. That's why it sputters when the engine is cold, and won't start when hot. Next time it won,t start when hot, hold the accelerator pedal to the floor and crank the starter. It may take a few seconds but it may start. To diagnose this problem a test called an "injector leak-down test" must be performed. Install a fuel pressure gage on the "fuel rail". If it wont hold pressure when the engine is off, there is 1 or more injectors leaking. Good luck.

OK, for starters a Ford AU Falcon does not have a distributor it has a coil percent. My bet is that you've water someplace on your electrics. If the engine will idle, even approximately, allow it take a seat and idle till it warms up. Sometimes this may occasionally evaporate the water that's inflicting the main issue. If it does not come well on it is possess then I'd pull the plug leads off separately and spray WD40 within every lead cap as good as giving every plug a well spray. If you could have entry to an air compressor use it to blow any extra water from within the lead cap and from across the plug earlier than spraying. The coil percent is rather good blanketed from the steam cleansing as it is tucked underneath the inlet manifold. But if you'll get to it then do the identical factor there as good. There could also be the principal engine loom connection field placed on the rear of the engine at the left hand part underneath the inlet pipe that runs from the air field to the throttle frame. Remove the inlet pipe and utilising a 10mm socket or spanner undo the loom connection field and separate it. Spray a beneficiant quantity of WD40 into each halves of the relationship field. They are the principal places I might be watching at. I desire this is helping. Good Luck.

I agree with Spenge. It sounds like a an injector problem or leaking fuel rail or pressure regulator. Get the fuel pressure test done. A bad fuel filter will not usually have such intermittent symptons. It would be a good idea to replace it though if you haven't in a while.

Sounds like a fuel filter to me.

Try a fuel injector cleaner. Its cheap and they work fairly well.
