Whenever I travel 10 minutes or so, the engine starts to miss on the same three cylinders. After I shut it off, it runs fine for another 10 minutes.The coil pulsar has been changed with no improvement. <br />The engine has 1100 hours.
Whenever I run the engine about 10 minutes, it misses on three cylinders. When it cools down it starts and runs fine. Replaced the coil pulsar, but this did not help.
