my 2000 v 10 started missing today. my y pipe har a rattle in it at about 1800-2000 rpms. when the miss started the rettle stoped. the external heat shields were cut off awhile ago so i know it wes not them. Is there a deflector or somethimg inside the y pipe that could have broken off and be cloging it? there is no check engine light on. this is stumping me.
Well i decided to go to the dealer right away. it was the coil pack. My dealer is a ford truck dealer. No cars. they deal in heavy truck and light truck. They have service from 7am to 11pm mon-fri. took them 10 min and found it. they let it cool and then changed it in about 1 and a half hr total. Bayshore ford in new castle delaware. the best.
