Hey guys. Just wondering what other causes of a bad misfire would be? Coil packs, spark plugs and leads have all been done correctly. The car tends to carry on and miss pretty bad when hitting 2500-3000rpm at 60-70km. Also idles pretty rough or while rolling. Can hear it in the exhaust but no leaks been found upon inspection. I'm stumped. Any other possible issues or any I should be concerned about?
