wanted to see, well my rpm's have been jumping a lil, making my car run shitty. i narrowed it down to my fuel line(im guessing thats why my check engine light has come on) but yeah, so i wanted to see how i can know what part of the fuel system is having the problem? if it is the fuel filter(gonna start with the most inexpensive) how would i know if that is the problem? if i take that out will it be obvious? with my fuel line: is it easy to follow? or does it go through places that it is hard to get to? i haven't seen leaks or anything, but fuel evaporates fast..so its kinda hard. i dont wanna buy one of those pressure checkers because thats about as much as it is for me to get a new fuel line. just lemme know on way to spots this problem please, so i can get my baby back out on the streets.

there are several possibilities that could be causing your problem but I doubt with all certainty that your fuel line is causing the problem unless it is kinked. I am therefore assuming that you mean in general that there is a fuel delivery problem.
You might have a vacuum leak, faulty MAF, weak fuel pump, DME on the verge of puking, idle air control valve malfunction, valves out of adjustment ...etc
A dirty fuel filter could have an effect but most likely would cause a consistent poor running behavior or a severe bog upon heavy load. If you have high mileage without ever having replaced the fuel filter, I would recommend it anyway. What have you done so far to diagnose the car?
