Misfiring, when my car reach on speed of 80 to 110. Little missing on idling speed also. I went to local workshops, they checked every thing on dignostic computer, but they found nothing. They changed new sparking plugs, fuel filter, and also cleaned injectors. I need your help to fix this problem.

check for a vacuum leak or one of your injectors may have gone bad.
