I'm having prob with my car I don't have any power and can't go over 60 mph and my floor is getting really hot and check eng comes on the code said miss firing I changed the spark plugs and wires and fuel filter didn't change any thing I think its my cat but not sure I could sure use some help thanks

 

i would say the cat is clogged as well...

 

Hot floor? I vote cat. Matter of fact when it's like that, I bet you can get out, look under the car and the cat will be cherry red (if sure 100%, bad cat). I advised you get that addressed ASAP. If it is clogged and you keep driving on it, further problems are sure to come up.

 

Ya that's what I was thinking thanks for input

 

CAT! is teh issue

 

I'll also vote for the catalytic converter. I had the very same symptoms with my SS....it was the opportunity I needed to do my SC install..lol
