Hello,
Just read you posts in the forum about cleaning the gas distributor by using STP fuel injector cleaner.
Could you send me some guide how to do it.
I got bi fuel S40 2003. And it started to misfire between 2000-2500 RPM. The problem is intermittent, I replaced plugs and coils without any success.
