Jerky/Vibrating situation when exceed 80 kmph - GMC Envoy

posted by User
when i reach 80/90 kmph, i can feel some jerky/vibration condition. When i did the computer checkup from Alghanim bumper to bumper, they couldnt identify the issue. The mechanic roughly adivsed me it might be problem with the Ignition Coils. I changed them but though still the jerk/vibration still exists.

My vehicle is GMC Envoy 2008. Kindly, please do let me know if anyone knows a good GMC Envoy mechanic.
