Default Car Running Like ***???

Ok recently it had been stalling or sputtering round 2.5k rpm, well I swapped plugs and wires seemed like it fixed. Ran excellent for a few weeks now. Still kinda sputtered a lil around 2.5k rpm but nothing too bad. Well this morning after been parked all weekend. Its running like ****. It feels like I'm running minus one cylinder or like I have a huge exhaust leak. I havent checked anything yet, but it idles regular and I dont hear an exhaust leask. Any Ideas? No Service lights. What should I check?

Could a clogged fuel filter make it run like that ?

ya could possible be something to do with your fuel system. maybe injectors might be clogged. i would check all the plugs again just in case and make sure there not bent or broke. o2 sensors can do that to but they are expensive but if your gasmileage has dropped alot then im 95% sure its your o2 sensors. but as i said do the easy and cheap stuff first. hope this helps ya

did i mention the gas was almost empty, like I ran it all the way down. Possibly picked up sum debris? I guess my *** is swapping a fuel filter tomorrow. Will anything get fucked up if I run like this for a few days. I've gotta cold and i dont feel like working on it rite now.

It's possible the fuel pump may have over heated from being run down and is starting to fail!?

Fuel filter, o2's, coils, MAF, and check the fuel preasure @ the rail to check on the pump.

BTW, o2's @ NAPA, the Bosh, they have a lifetime waranty, exchange them whenever you want, and only about $60.
