I have a 99 F250 that does not IDLE on CNG. Also when you tramp on the thorottle, it switches over to Gasoline. I have so far drained the tank, replaced the filter, i removed the compuvalve and tore it apart and cleaned the jets inside but still the same problem. The only other mechanical part is the Regulator. This is not leaking so i figured it was good. Any suggestions?
By the way, these compuvalves are not that difficult to clean. Just takes a little bit of patience and general mechanical knowledge.
