Hey all, as some of you know i just got a 05 zx4 st. I noticed today when it was cold/snowing out on my way to work the car would hesitate/jerk randomly. Seemed to happen more under 50% load but cant really say 100% sure. NO CEL or anything to tell me whats wrong. Did not happen after work 1 single time, so it seems like it mainly happens either when its really cold or snow/rain. But again cant say 100% sure that is why. I am thinking either spark plug misfire, coilpack, or something electric, maybe even timing chain?. Only had the card for about a month now and only have 82000 miles. Just wanted to get your opinions as to what might be the problem or if anyone else has seen this before.
