Hoping someone can help. I just finish the z31 ecu/maf swap into my 82 l28et. Im having a poor cold start issue, fires up then stumbles and dies, unless I give it some throttle. Also when fully warmed up, intermittanty it will stumble and die out when im at a stop.
I've read some where that after this swap there is a lean cold start issue. I don't have a cold start injector, my timing is at 24 btdc, fuel pressure is at aprox 35 psi. I wired up the ecu and maf accordingly and swapped out injector 5 and 2.
Anyone have any suggestion?
