I have a 2017 mustang Ecoboost automatic, when I am at a cruising speed and take my foot off the gas pedal the car seems to coast at that speed for a few seconds before the engine starts slowing the car down without braking! This feels like the up shifts are stacked and the d shifts are weak. I brought my car in and the dealer said everything was normal. They hook it up to the diagnostic as nd that's it. I feel like mechanics rely to much on computers without having a gut feeling. Please if you have a answer please help? The car has 100,000 miles on it!
Well off in my video will fix it by cleaning the throttle it's called make your car run better with a little spray cleaner Scotty
Thanks sir I will try it, I'll let you know how it works!
When was the last time you changed your transmission fluid and filter? As per the maintenance schedule?
