My 04 f150 died and found out it needed a fuel modual,I put a new one on and now it misses, any sugjestions

 

Is there a CEL (check engine lite), lit on the dash??

If yes, then you need to retrieve the codes. This will give you indications as to what the issues are. Post the codes and a vast array of knowledgeable folks can help.

Other wise its a roll of the dice
