I need some advice on my 95 2.5 SE. Lately it seems like it's really doggy and underpowered while driving. I am going to change the plugs and wires soon and a complete tune-up. I'm not sure what it could be. It seems to be knocking quite a bit especially when the air conditioning is on. Any ideas? The only mods I've made to it are the SVT airbox/K&N filter and the SVT inlet pipe.
I'm stumped. Could the secondary runners not be open? I'm not sure if the Duratec is like the SHO or not.
All help is appreciated.
