Hello all,
Problem: engine stumbles with acceleration especially when AC is on. Problem appeared after some work was done in shop for belts squealing (I think belts tension was adjusted, squealing was also associated with AC start). Now no squealing, but engine stutters and gags from time to time when accelerated or gives jolts at traffic light stops, significantly worse when AC is on.
Any suggestions?
