I have a 2005 ford ranger 3.0 and I have codes for miss fire on startup, random/multiple cylinder miss fire. And then miss fire for cylinders 1 2 and 6 but that’s not consistent it will change somtimes which cylinders. It only misfires at idle it’s worse normally when it’s cold or just when it’s been sitting at idle for alittle bit and feels completely normal when driving it I’ve replaced all spark plugs tested the coil which the primary tested 1.4 1.4 and then .6 don’t know if the one being lower than the rest is an issue but it was inspec according to my Manual. And then the secondaries all tested 13.4k so I believe my spark is good. Fuel pressure is good at 65psi Ive replaced the fuel filter and all the fuel injectors have been replaced. I’ve done a compression test to all of them they were all the same besides cylinder 2 but it was only like 10psi difference don’t think it’s possible for the one cylinder to cause the rest to misfire like they are but I could be wrong. I’ve checked vacuum and im getting around 17 at idle. If anyone has any ideas on what it could be it would be much appreciated im kinda running out of ideas on what it could be or maybe I’ve missed somthing.
