Hoping you guys can shed some light on an issue I'm having. I've been chasing a misfire on my Cruze for about a year. 120k miles now. The misfire happens only on a cold start (though sometimes under high load high rpm situations) and typically sets off a flashing CEL and Service Stabilitrak warning.
Usually goes away after about a minute and then runs like a top. It has new plugs, new coil pack, new injector on cylinder 1, and it still misfires. Gap is verified to be within spec. Just out of ideas honestly. I've read other threads and I'm not coming up with anything. At this point I'm considering compression test/leak down to rule out internal issues. I know it has a (probably internal) coolant leak somewhere as well but not enough to cause a misfire on other cylinders or white smoke or anything but just want to remain transparent here lol.
Ideas?
