I have had the same issue.. I changed the fuel filter and that wasnt it... They changed my plug wires and they changed my number 8 coil. That fixed it for about a week, but it started again and they said the 8 coil went out again. They replaced it again, but the next day after getting it back I can still feel a little mis, like its a little sputter. which is how it all started the fist time I replaced it.. Do you have any Ideas on what might be the problem.

Look on frame rail near fuel tank, on drivers side.

I have been told that my 1999 Cadillac Deville may be experiencing hesitation and rough running because the fuel filter may need to be replaced. Are there any instructions for that?


First we need to check if really fuel filter is at fault for rough running. Open the bonnet and pull out fuel pipe from the engine. Put this pipe in a clean and empty clear bottle (so that you can see the pipe) and now switch on the ignition but do not start the car, just turn it on. See the flow of fuel, if its constant then rough running is due to something else and if your fuel filter is really clogged then petrol flow will not be constant. To change the fuel filter, get under the fuel tank and locate a plastic cylindrical component with two fuel pipe connected to it. This is fuel filter. Buy a new one and replace. Make sure you check the pipes for any fuel leakage after you have connected the new fuel filter.

My 92 5.0 thunderbird started to idle rough then after a couple days began to surge and when you accelerate car runs rough to about 2500rpm`s but seems to be getting worse


It sounds like you have a fuel problem. You should replace the fuel filter before trying anything else, and when you do, dump the old one into a CLEAN container and look for water. Dirt should be taken care of by the new filter. If you do have water, you will see beads in the container. Get some isopropyl alcohol or gas line antifreeze from your automotive dealer.

All of the sudden my 1999 328i started running bad idle irratic, dying ect. so i changed the fuel filter no change. i hooked up obd and got several codes. ended up replacing throttle valve,mass air...


YOU COULD HAVE DIRTY FUEL INJECTORS OR A FAULTY FUEL INJECTOR.OR YOUR GASOLINE COULD HAVE WATER IN IT.AND RESTRICTED EXHAUST LIKE MUFFLER OR CATALYTIC CONVERTER WILL CAUSE ROUGH IDLING AND STALLING.

I need to find the fuel filter on a 2004 saturn ion 3. The car is running rough, and throwing a P0300 code at me. I have replaced the coil pack, plugs, both oxygen sensors, and the catalytic converter....


Check your plugs, check the ign module, test the injectors,take a fuel sample and make sure there isnt water in your fuel, if all these test good perform a compression test. if the compression test fails replace the head. if the compression test is good. check the timing

Car will not start without spraying fuel into intake cant tell if fuel pump is running is there a reset switch and where is it located its a 1997 eclipse 2.0 non turbo


there is no such reset switch located in the car. First turn your key on and listen for the fuel pump to pressurize the lines. Then check to see if the fuel is leaking from the  filter. If it is you may have got the connection wrong. If thats the case your engine is not getting the proper fuel pressure to run. Hence its sucking air. If that does not work you might have a bad fuel pressure regulator sensor that is bad. Its located by the TBI. Reference a Haynes manual for replacement.
also if you did not fill the new filter with fuel then you have air in you system and engine will not run. so try taking it off and filling it with fuel and then replace it.
--------------------------------------
turning ignition on removes air from fuel lines and primes the fuel system. filling fuel filter with fuel is irrelevent, as lines need to be clear of fuel upon installation. leave ignition on after installation for roughly 30 seconds-one minute. this will prime the fuel lines and remove air and most water from the system. if problem continues, fuel injectors. this is a common problem in 90-92 camaros. if cannot start car, you'll need to replace every injector, as it's not cost-effective to diagnose every injector. roughly 300 dollars in quality parts, roughly 4 man hours of labor. if rough start that requires push on accelerator (try this), run the car with fuel injector cleaner. this should salvage you injectors. if this helps proformance, starting, then for the next 3-4 full tanks of gas, add stp injection cleaner for every tank of gas. be careful, as this does not restore your injectors, but it helps clear away deposits which are common in multi port injectors.
