i got a set of bosch uber platinum quadra-power 5000's (the ones with 4 prongs, i dont remember what theyre actually called) so the plugs are about as good as theyre gonna get, as for the wires, replacing them doesnt fit into my budget at the moment unless absolutely needed. if im still having problems after i put the new injector in i'll start looking into the other stuff. hopefully the problem will be cured with the injector because funds are nearing an all time low.
