Ok so last week my car wouldn't start , after changing battery and starter motor it started but was blowing horrible blue smoke so the turbo was then changed... it starts perfectly but when its idling the revs jump and when it shifts from 1st, to 2nd then 3rd it is sluggish. It has issues changing from 3rd into 4th then runs perfectly... wtf is going on with it!!! I'm a girl so I don't know **** and I'm sick of being ripped off by mechanis 2007 CX-7 Turbo .. Automatic transmission /Petrol

 

Welcome to the forum
You need to have your ECU scanned ...there will be DTC(s) based on your report of the engine running characteristics.
Why was the Turbocharger determined to be bad if all that was needed was a new battery? your 2 issues are not related.
