My 2009 Chevy traverse has a misfire on 2 cylinders only

(2009 Chevrolet Traverse)
My 2009 Chevy traverse has had problem after problem. Now it is only misfiring on 2 of the back cylinders 3&5 I believe I have changed plugs, coil, injectors, and had the computer sent off to be tested they said it was bad( somehow 2 cylinders misfiring) they fixed it I put it on it didn鈥檛 work sent it off again. They said it was bad and fixed it again can the car keep burning up computers? Or any ideas how to stop the misfire. Dealer did timing about 3,000 mi ago I鈥檝e replaced cats and o2 sensors as well. Compression is good.
What seems to make the problem better or worse? Same
How long have you had this problem? Almost a year cannot drive it like it is

Since the misfiring cylinders have been identified - the following test will reveal culprit :

Ignition spark test

Fuel delivery test - injector balance

Compression test

Vacuum leak test

Assume nothing - thorough *TESTING* is required!

Furthermore I do not understand why this relatively simple repair has turned into such a dilemma - any experienced auto repair technician should have had no problem with successful diagnosis and repair - period!

I hope you can find qualifying personnel..
