How's that going to clean your inlet valves?
I'm not fussed about the valves Ian, my injector is my objective as I agree, if this goes on the fuel rail, then this will treat everything from the rail to the exhaust Cat.
If I didn't have this misfire then I wouldn't be trying this. But I now my valves aren't the issue as when warm, the car is fine .
We shall see. If I get better mpg after, and a better performing car,then it's money we'll spent. You can't have clean valves all the time.
