I swaped a B18a1 out of a 91 teg. I'm using the teg computer ODB0. I got it together and all was good after figuring out a bad main realy. It ran great but smokes alittle. I think it has a stuck ring. The swap was sitting on a garage floor when I bought it. After I had beend driving it awhile I started to get a Check Engine light. I checked codes, it's a 43. I didn't think this was posible. That code wasn't in my book. So I cleared the code and drove it more. It cuts out, but feathering the gas pedal keeps it going. It's like a bad spark plug wire or something. I rechecked the codes and I get 4 slow blinks followed by 3 short ones. I replaced the O2 with a new bosch one. Same thing still. I installed my apexi turbo timer and it has an O2 reader. It's at 20.00 most of the time. on the highway crusing I'm at 15.0-16.9 I'm not sure if this is the problem? Is the O2 reading wrong? Is the smoke causing the O2 to go bad? It's a light smoke not that bad. More so on hard accels. The old O2 wasn't oil fouled looking. And the code came back 1 min after putting in the new O2.

Is a code 43 even possible in an ODB0 ECU?

Thanks for any help

 

check the fuel pressure along with the injectors and also make sure the fuel filter and plugs and wires are in good shape.
