I did a b16a swap into my 90 CRX DX and it was running rich so i brough it into the shop and the guy said that it was because the O2 sensors were no good and there was a leaky injector... he replaced both and then I went and picked it up. Now it seems to be worse, when it went in it was only throwing a code 23 for knock sensor. Now went and picked it up and was driving home it was throwing a code 3, 6, 7, 21, and 23. WTF did he do to my car???? OH and by the way its still running rich. What could be wrong I"m gonna try to just disconnet the batter for the night and then see what it does 2morrow. Can somebody give me any ideas of wtf is wrong with my car.

 

leaky injector? how do you test for that?not shure about your problem but i would go to a diffrent shop and see what they say?

 

You better take it back and make him fix it!

 

I would bring it back and have him fix it, however it took him 2 weeks to just do that bcuz he was really busy and just tried to do this on the side when he had a chance so if I bring it back to him I think that it would just take him another month

 

Well I took the negative line off the battery for the night and it reset the car and the check engine light doesn't come on for any of the codes it did b4 except the knock sensor which is just a bull **** code anyway. However I dont think that it stopped running real rich, what else could it be the guy in the shop said something about oil getting on the dizzy and that messing up the firing of the injectors. Or the Ground for the ecu is bad wtf is he talking about? And how can I get my car to stop running so rich?
