i have put in a B18A1 in my friends car it is a 1994 civic coupe with a wierd harness on it i really have not altered anything but everytime i pull a code i get a new one like the first code i got was 14 and 41 14 was EACV, and 41 was oxygen sensor heater, i replaced the EACV one because i was using a substitute from the 1.5L sohc motor and got the one for the motor i used three different o2 sensors and it is still coming up it is not the 4 wire 02 sensor either it is one wire and when i replaced the EACV i got code 10 which was air intake temperature sensor i replaced that and then i got code 8 which was TDC, i think i have a serious wire problem this is not my harness my boy got this harness modified by the person who had the B18A1 in his eg. when i drive it just normally around at quarter throttle the car feels like it kills the fuel also and then it gives gas again so this is reall confusing me? ps. all the stuff i have replaced it is still showing up the codes, and i have reset the ecu to many times
