The car is a 87 non-turbo w/ a 89 turbo motor, wiring harness, and ecu. All clean. The car acts as if it's running in open loop ALL the time. It will lean out like crazy at idle (19:1-15:1 afr) I'll tap the throttle to make it rich out so it won't run hot, and sometimes it will idle right around 14.7:1 afr, but rarely. When driving down the road i'll see readings of 9.5:1-13:1 afr. I'm seeing code 42, and that's all. I seriously need some help, because i've been working on this for a month now. Ask me if you need any more info, i'll be able to check again tomorrow night.
BTW, the car was running on a 87 turbo ecu and wiring harness, but i switched it back to the 89 ecu and wiring because it was a clean harness and ecu (taken from my 89 supra). The car was having the same issue w/ both harnesses and ecu's.
