i just got a gs and it keeps fowling the number 1&4 plugs and i changed the plugs and the coil pack and its still spitting and sputtering... i dont know what the problem is... can some one please help me? i dont know much about the eclipse's im pretty sure it has a 4g64 motor... is that a motor that is worth boosting? or can a 4g63 be put in there fairly cheap and easy...from all the threads i read doing a motor swap in a 2g is a pain in the a@$, but i just figured id ask again... if any one has any suggestions that would be great thanks
