Not quite... Tons of posts in the forum reporting single cylinder misfires. That's why people swap stuff between cylinders to isolate bad components. Did you read codes yourself or going by what the mechanic said? You sure all codes were fresh and not stored from a previous fault?What I CAN tell you, is that if you have a misfire on 1 cylinder, mainly due to a bad coil, it will report codes on all cylinders. My guess is from the timing getting messed up.
I had a misfire on all 10, and my mechanic tracked it to a bad coil on #6. Replaced only that one, and it's been perfect.
