so over the winter i built a ls vtec motor put it in and tried to start it when i did it was only running on two cylinders had spark to every cylinder but only 4 and 2 where shooting fuel out of injetors so i switched injetors around to see if the were bad but still sprayed out of 2 and 4 so i changed resister box still did same thing at the time i was running a obd1 ecu and distributor but obd0 injectors so i changed back to obd0 ecu and obd0 distributor and obd0 injectors then it sprayed out of all four i was like sweet put rail back on manifoild went to start it up an while tryint to turn it over it was backfiring checked all my grounds checked by distributor order it was right any help im running a b17 head so i figured sticking to obd0 would be the way to go
