New member, here due to a Cylinder 1 misfire. 2017 chevrolet cruze LT, automatic, 1.4L with 37k miles on it. From what I'm seeing this is the 2nd gen and not a lot of information is out there. Tons of engine pics for the 1st gen, but not 2nd gen. I've replaced plugs, changed out the ignition coil. Still have a misfire. There are some that say it could be a pcv valve or evap purge valve. I purchased a pcv valve, but the bolt that holds it on is not a standard torx, and it's not even a mortorq twisted. It looks more like a 5 point star fish. Dealership told me they don't sell the tool, checked with the snap-on truck that was there that day but they didn't have it either. Anyone know what the tool is called?
