I can't seem to figure out why my car is idling so damn rough. It only started doing this after I had my new clutch put in. If the car is at about 1k rpms, it's smooth as silk, but when it drops to normal idle speed (500-750 rpm) it starts to shake pretty bad, I can see the hood shaking. I just did a search on what might be causing this and I will try TB cleaner tomorrow and I'll probably do plugs/wires too, but where is the fuel filter located at and how hard is it to replace. My car has 174k on it so I'm not doubting that may be the problem. Any feedback would be great, thanks in advance all.
