Review on Liqui Moly 2001 Valve Clean by Madansaireddy Aldridge

Products from Liqui Moly work! I have a 2014 Ford Expedition that would shut down in the morning until the engine was warm. I had a friend run a test on his computer and it showed a misfire on cylinder #8. I replaced the spark plug, coil pack and injector on cylinder #8. The misfire did not go away. I used two cans of Liqui Moly valve cleaner along with a Liqui Moly fuel system cleaner at the same time with a full tank of gas. I did not start the car for 8 hours after adding the valve and fuel cleaning additives. I have done this treatment twice with two full gas tanks. After some aggressive freeway use of the engine, shortly after the second treatment was added, the check engine warning light went out and the engine would not stall, nor would the engine stall. I plan to repeat this treatment on my engine every 6 months.
