What's up guys... I've run into a bit of a problem here. A couple weeks ago my car (ka-t s13) was running rich and dying due to a bad vacuum leak. Got that fixed up and she ran good as ever, dont have insurance on it though so it sat for about 2 weeks.
I went to start it a few days ago and it ran fine, with good AFRs, for like 30 seconds at most. Then it begins to run rich, have bad/delayed throttle response, bogs and dies. It does this every time I start it. It also shoots out some black soot as it bogs/dies. Checked for codes and got the all clear code 55.
I now have the upper intake manifold pulled off. The IACV is spotless, the throttle body is pretty clean too. I hadn't checked those since I bought it so I figured I'd do that first. Just wondering what else I should check. I haven't run into this problem before, anyone have any ideas?
It's got an enthalpy tune, t28, 550cc injectors and a z32 maf. Let me know if you need more information, and thanks for any and all help
