I am working on a small project right now and need a little help. I have a 90 civic hatch that someone completely stripped and I got for free and a d15 that ran in another hatch that had no check engine light and no problems. After putting the motor in and getting it running I saw that I was throwing codes 4 and 16. I checked my haynes manual and checked what they were but really can't figure out what could be causing it. Thanks for any help you have or suggestions on what can be done. Thanks again for all of your help.
Oh yeah I change the distributor out to see if that would help out with code 4 but no luck????

 

did u reset ecu?

 

Yeah I reset the ecu but still throwing the same codes after changing the distributor???? Don't have any clues to whats up yet. Thanks for all the help again.
