hello. I just bought this car .Drives ok but even after very long drive, stoping at red lights or in heavy traffic ,my revs from 1000 ups to 1800 for 15 seconds nd then returns to 1000.This happens all the time.My mechanic suspects EGR valve.I put redox fuel system cleaner nd did 58 miles.Is REDOX suppose to help? And if ,how long Redox takes to work?Anyone with same problem can guide me in right direction.Hoping for replies.Thank you nd god bless you all.
