ok so i did a pressure test on cylinder 5 and it was 120 psi. Is that where it should be? So now what could be a cause of this misfire? As for the connection there is a loose one, i just dont know where it is supposed to go. Its the one coming off the "T" under the SC snout. Of the two lines its the one farther away from you if you are standing at the front of the car looking at the engine. The one end is connected to the "T" but the other end is just hanging loose not connected. Where is that end supposed to go? All your comments are appreciated. Thanks in advance.
