so i have an 2001 ford f150... my truck sometimes has a rough idle and some times has a rough accelration feels like its missfiring.. engine light comes on and goes off every once in awhile have been losing gas milieage ... but i cant check what the OBD is saying because the fuse keeps going out on the fuse box i put new fuse in and it just pops that one instanly... any ideas?

 

Make sure the cig lighter isn't shorting, the DLC and the lighter are on the same fuse..

 

ok i'll chk that thanks...
