so i was driving the 2005 screw 2 days augo and after 3 weeks of sitting i noticed it had a missfire... so first thing i did is looked for codes... no code... second thing i did was changed the plugs still there then i asked my mechanic friend to have a look so we looked for about an hour and did a test to see if any coils were bad and after that we determened the driverside very front one had a bad coil so i replaced the coil and the damn thing still misses.....
so i was looking under the hood today in just disgust and i notices one of the vaccume lines was under so much load that it had collapsed in on itself its the line that goes off the throttle body ion to a t that goes to the back of the roush charger and then goes in to the head and the part that goes in to the head has been sucked that tight so i have no idea i need help and also it releases when the truck is off..... thanks please give me some ideas
