Cleaned EGR TUBE, replaced EGR valve. Ran great until 3 days ago. Noticed a decrees I fuel mileage on Monday and Tuesday had the car backfire and lose power at times. EGR was sooted badly as was tube. After cleaning g and replacing there was no difference in performance. Going to pull plugs next. Any other thoughts? 214k miles, uses some oil between changes but did get 26mpg until this week.
have the same problem?
