I am new here I've been looking for questions and answers to issues with my 2005 GTP it has a slp short air box and lid, and that's all I am having problems like while I'm driving in the rain and hit a puddle it sounds like my cat fell off, as well when I give the accelerator all it has it has a dead spot you can here it in the whining of the s.c. As it seems to have a miss at low constant rpms I have changed the plugs to a hotter plug and replaced all my coils and wires as well the rear plug got cracked in the changing process it was replaced.. If anyone could help with this I would appreciate it
