so i put an f22a4 engine from an 90 accord ex into my 92 prelude. it shoots me a code 9. i put in a new distributor and still code 9. so i made sure timming was good. which it was. i think its the ecu. its the one for the 92 lude. so does anyone think i need to change it to a 90 accord ex a/t one? and if i do does anyone know if i would have to change any of the pinouts? p.s. that smiley is me freakn out!
