today was the first day ive driven my car since i soldered in the new coilpack connector from the main harness. everything seemed to be doing fine but as im driving home from work id give it maybe 3/4 throttle and id feel it sputter at 2k rpm and then shoot back to normal? it was like a sudden loss in power for that moment. could solering the wires cause any sort of current change going to the coilpacks and then cause them not to have enough power to make a good spark? i did a good job soldering or at least it looks good its not a big glob or anything its a smooth straight line with good penetration. and then i shrink tubed each one. then the other thing i can think of is maybe my plugs? theyre platinum/irridiums and only have 6k/7kmiles on them and i dont know why they would cause a sudden sputter at 2kRPM? what could be happening and how can i check for it?
