2006 lacrosse idles slightly rough and sometimes jerks slightly under light to medium accelleration. I went to replace the fuel filter, but I can't find the filter.

SOURCE: Check Engine light & slight hesitation

I had the exact same problem. The mechanic found a spark plug that was leaking on the back of the engine that was a pin to get to.

He replaced all plugs and wires and I no longer have this problem, so you may be onto something with the plug wire being loose.

I would suggest a few things ... first and the most important... check that you have the wires in the proper order on the distributer. next have the timing checked.

Try replacing the PCV valve, and spray the carb, or throttlebody, with a good carb and choke cleaner.

If you can determine the ignition system is ok, I would look at fuel pressure and the fuel filter. If the distributor was loose you may have to check base timing.

I have an 2006 f150 5.4 liter..when I take off the truck sometimes jerks, and when I go to accellerate to pass, it seems to drag and the emission light comes on. What could this be?
maybe low fuel pressure or a vacume leak i had a 04 f150 4.6 i had a vacume leak on the back side of the motor it would surge at idle and was slugish but it was a bad leak

Although is could be a fuel filter, it could also be a fouled spark plug, or a bad spark plug wire. Once you've ruled these things out, the problem could be the TPS (throttle position sensor). This controls your idling speed under all conditions. A faulty TPS will usually idle fine when the engine is cold but once warm, will tend to sputter and in some cases, stall.

A tune up would greatly help. Plus change all filters especially FUEL filter. Another common issue w/Benzs is vac lines cracking, breaking etc... causing similar symptoms you listed. Most are buried in/around and under air filter, inspect all the vac lines closely. But again a good healthy tune up will give you a good "ground zero" point for reliability.

Can't find the fuel filter!
I have a 2002 Lesabre but suspect it is in the same vicinity. Look under the car, drivers side under the passenger door towards the middle of the car.

Sounds like there is a blown piston, to be sure have a compression test done on that #2 cylinder, if the reading is low, then you'll know.
A friend of mine had a 95 that did simular things only a little more,
it started smoking, dash lights flickered, etc. Finally, he had to get rid of it, the piston rod went through the engine block.

I assume the check engine light is not on. I suspect you may have a slight vacuum leak, especially if it idles a little rough. Check all under hood vacuum hoses for cracks and make sure they are all connected.I also highly recommend you replace the fuel filter if you have no done so.

While at idle, SOMETIMES my car jerks and feels like it will shut off.
I had that problem with another one of my vehicles. It ended up being the fuel pump. The problem was that I let the fuel level in my vehicle get to low, and that the fuel filter inside the pump had gotten debri from the bottom of the tank stuck in it and it was starving the vehicle for fuel. Eventually my vehicle wouldn't start. I had a tow truck driver tell me what the problem was. He banged the side of the fuel pump real hard and the vehicle started right up. I eventually had to replace the fuel pump.
Hope this helps.
