Ok so sometimes when i start my bullitt i turn the key and it just makes that engine starting sound, but it won't start immediately until i let of the key and then it slowly turns on. Sometimes it starts right up other times it just makes that nasty start up sound. Do i need new spark plugs or what? If so specifically what type should i buy?

 

i don't know, i have the same problem with my 98 gt.

 

I would do a full tune-up wires, plugs, and fuel filter. Mine is sort of doing that right now and I just changed the fuel filter and Im waiting on my new wires to get here so I can see if this helped or not.
