Getting missfire in cylinder 4 need to know how to fix!!! Any help greatly appreciated.

 

dont panic yet, could be as simple as a fouled plug. i would start there with taking a look at the plugs and wires.
any other info on what the car is doing / how its feeling?

the #4 plug wire can catch a lot of heat from the turbo (as we saw when the switched the way the wire when the problem was discovered in 03), so perhaps there is an issue there.

 

I already put new plugs and wires and a screamin demon distributer on it and it still throws the code.

 

i immagine you reset the computer afterwards (duh but ya never know)
could try to check to make sure the injector is not clogged as well. any noticable loss in power? boosting the same? feels the same? any shakes shudders or noise? anything noticable under the hood? any smoking from the exhaust? etc?




btw, what part of pa you from? im origionally from there!

 

Wires & plugs would be my first suggestion. Maybe try putting the stock coil pack back on. You never know. Also did it have the misfire BEFORE changing the wires/plugs and coil pack?
