blocked off gas/vacuum line??
I have a 04 and its had some major hesitation when putting a load on and in low rpms, to appears to have a bad misfire. anyways I was taking off the gas tank in order to get to the ignition coils, and when I got the tank off I noticed a hose with a screw in the end of it. deff not something from the factory. so I was wondering if someone could shed some light on what this line is and where it goes, as it may be causing the problem. the screw is in the bottom left in my hand lol. thanks oh and if someone could direct me to a write up on how to remove the ignition coil, that would be awesome
