does any one know how to adjust the mixture screw on the manifold without a sun/krypton machine. The car sounds like a bag of spanners when on tickover and erratic, but goes like stink when driving. Please help cheers

 

When mine did similar to this i found 3 injectors were beyond their tolerances. They run a little lean from factory so this really doesn't help!

Don't take my word for it but to richen I think you turn the screw anticlockwise.

However I don't think EFi will ever be perfect or as smooth as mfi in standard forms.
