Ok 1991 honda ef hatch 170k on mother doing swap I did everything right all the wires look to be right tried alot of different things. I keep getting error 4 and it will idle all day long but as soon as I hit the gas it dies. I am not sure what to do now, I have gone over eveything and all parts came out of running crx that was converted from DPFI to MPFI
