At Idle I have miss fires on cylinder 2-4-3, I have no idea what is causing this. I changed plugs and wires, checked ohms at coil packs read all the same, I also have autolite plugs gaped at .040. but wot is perfect no kr or miss fires at all, what could be causing this, I have a scan to look at if that helps. TIA

what is the primary miss fire cyl. how many times each cyl. miss fires and also how is your egr. do you have it turned off. and if not maybe your egr is sticking.. but to me your #3 cyl. is the primary miss fire if you can find that out i can assist you more.
