Glad to here you might have solved your problem , I was leaning on the ignition thing , thought that was probably the cause . Sorry you had to spend so much dough though . Remember if it seems better and still has some probs like i had , look at that coil pack , it might be weak . Yes its not a matter if they work or not , they will get weak , shorted windings inside the pack will cause a weak secondary voltage , and not actually fail all together . Not to many people consider this when doing tune ups but the hotter the spark the more complete combustion youll have. I always check my secondary voltage when i have a no CEL situation and has remendied many problems quickly. Coils are like a transformer and they have windings , Sometimes in oil sometimes not , doesnt really matter , half that coil can short out , sometimes the insulation gets so hot it melts off and actually will leave you with only 5,000 volts . Thats not good , most coils produce 10,000 to 20,000+volts , if Im not mistaken , its been awhile. When putting in quality wires , which are bigger , sometimes , And create less resistance , they can actually help , but never fix the problem . Before you do a wire change make sure you test the wires with a ohm meter and flex the wire along its path make sure there isnt high resistance and no opens . The stock wires are great . You dont need hi-po wires to send that kind of voltage , of course if you modify , youll need a hotter spark , thus a bigger wire( at least 8mm)Bosch is not gonna make your x run better , always look at size . Sorry you got sold on hyp , but id like to look at the wires they condemed , Im still not convinced thats the problem . Especially if they say it was the #3 or #4 wire , because those 2 wire always get the weakest spark = longest . Let me know whats up.
