for some reason, on my first post, i said oil filter but what i really means was the fuel filter. i changed the fuel filter, plugs, plug wires, rotor and cap for under 10k miles (changed those when i first got my car

), also oil change every 3k miles. fuel line to the filter still fine, no cracks or leaks at all. Checked every hoses and they are fine and secured. just clean the air filter while i changed the oil about 200 miles ago (using injen cai). havent check on the fuel pump yet, any idea how to check the fuel pump? the car runs fine but it'll choke for some reason like i mentioned above (the first time happened was about a month ago, and it's happen more often >_<).
thz for the inputs guys. keep it coming so i can figure it out asap and post it here.
oh, a guy who work over autozone (i know they might be wrong, but it worth a try though

) said it might be the timing chain. i'm not sure about that but sounds reasonable since i didn't have it check when i get the car. but will the timing make the engine choke during acceleration or deceleration? thz
