okay, some days it idles great. some days....not so great. What happens is that the idle fluctuates. When I press in the clutch it drops down, seems to stall for a second and then idles back up like normal. sometimes it just drops. I talked with my friend (a honda mechanic) and he says that it sounds like a fuel problem. I told him i have replaced the IACV and cleaned/adjusted the thingy under the throttle body. I have a new fuel filter at home but can't get the bolts undone to replace it. ill try that next. any suggestions or ideas?
