Evening All,
I have a 1998 3.9ltr V8i Discovery Automatic gas converted.
When running on petrol the engine backfires between 1000 and 2000 revs, after 2000 revs the engine doesnt backfire as bad and doesnt feel as rough. When I pull up at a junction or roundabout the engine stalls or I loose power and struggle to get going again. However when I switch over to LPG the engine runs like a dream.
So far I have
Changed the fuel filter
Tested the fuel pump (working)
Tested the fuel pressure in the rail, pump (all good)
Tested the fuel pressure regulator (works fine)
Tested the fuel injectors with a stethascope (firing ok)
Tommorow I am going to change the spark plugs.
Has anyone got any other idea's.
Cheers
John
