new here but been watching all the sas conversions as im doing my own. my 91 is idling fine but in rev or drive the motor seems to miss real bad any ideas?

 

when mine did that it was the fuel filter...easy to replace and cheap, i'd start there, if that doesn't do anything check the fuel pressure

 

new fuel filter, map plugs wires cap botton etc fuel pressure 61 psi in gear
