Hi,
Can I use EB injectors on my EF..I heard they're the same..

I was using AU ones,and they consume approx 20% more fuel,plus it causes it to run really rich..

Yes, same injectors, 19lb. AU injectors shouldn't overfuel, they are only 20lbers. Use them in the wagon and there was a slight improvement. Check your MAP sensor hose.

Hmm fair enough,
It's running crazy rich and drinks heaps..
So far I've changed oxy sensor,map sensor,spark plugs ,water temp,and reconditioned injectors too..they just have bik idea why its running this rich..after the diagnostic test,it was concluded that it is the injectors..

check the vacuum hose to the fuel reg or maybe your fuel reg is cactus.
