I have a 1986 Merkur XR4Ti with a 2.3 turbo motor and 117,000 miles on it. The car ran good, except for a hot start problem I had. The injectors would leak fuel and flood the motor, making it almost impossible to start until it cooled down. I tried many fuel system cleaners with no improvement. I tried one can of your injector cleaner, and after one tank of fuel there was a great improvement. I poured one more can in and went on a 300 mile trip. The car ran perfect, quicker and smoother than ever, 22 mpg, and my hot start problem is gone! I was ready to change the injectors, now I don’t need to. I still can’t believe it. Thank you for this excellent product!
