Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

2002 pontiac grand prix 3.1 is slow as hell. New spark plugs, new spark plug wires,new fuel filter and, i cleaned the MAF. 0-60 in 12.1 seconds now before i changed all of this it was 0-60 in 12.9. It wont spin the tires and the tires are bald as hell. what is wrong with it?
 


even in perfect running order my tires will barely spin. my 0-60 is about 8 seconds.
just get a 3.8 s/c and do the swap.
 


it really depends on the cost of the engine and wiring harness. you will need engine mounts from a 3.8 car as well but that shouldnt be that bad for you.
