Vehicle has slight misfire @ idle when taking off from stop will hestate on acceleration intermittent but then kicks in also will hesitate at highway speeds intermittent. Have changed out oil, oil filter, air filter, plugs, wires, MAF sensor, air box, and coils. Not sure what else I can do. Anyone have any suggestions? Really could use some help. Can an 02 sensor cause this much of a problem or maybe an OCV since it is all on 1 side of engine cylinder?
