I just threw mine out last week and put KME in. One injector was leaking. The rest held, but the mileage on gas is 150,000. So replacing them all is over $1000. It also let the evaporator out. This is how it came out to buy lumber and I have full freedom. In addition, I led the installation along the factory harnesses, so finally there is access to some components. And there is no such mess under the hood. I still have to move the evaporator to another place so that it does not interfere. And at the same time changing the circuit from parallel to the way it should be in this car, i.e. serial.
