My car is misfiring but the plugs are brand new and same with the wires and coil pack is fairly new so what would cause it to misfire?

 

Bad/clogged fuel injectors, bad fuel pump, worn intake manifold gasket, plugged/clogged fuel rail to name a few other things.

 

ok thanks ill look into it

 

Depends, when does it misfire? Does it misfire when you accelerate? If so that's fuel injectors, run some gumout through the tank. Does it miss while idling? That's ignition, check your plug gap, too big or too small will cause a miss fire.

 

thanks for ya help it misfires ever time it runs lol...and i notice its performance is garbage
