hey guys i've been trying to find out whats causing my misfire at idle and low rpm+ occasional backfire:rl:.... i found out a couple things off which i could fix. but now im down to this...
the white wire coming to the maf thats supposed to have 5V is reading 0.
does someone know off the back where that wire goes is to? im sure its the ecu but if someone is knowledgeable enough to point me as to excatly where?
thanks in advance
sr20det redtop in 92 '40
other 2 wired check good for ground and 12v

Black w/ white stripe is... 12V+ ignition on.
Black is ground wire to body chassis.
White is ground signal that goes to ECU.

any idea where on the ecu exactly? i think my next step is to check that(5v white) wire for continuity right where it comes into the ecu. and yes the black wire is good(ground) , and white and black wire is good too(12v).

If not you need to
