So I finished my OBD-1 B18B1 swap into my 96 civic DX last week. It idled fine until last night, it seems to be around 300rpm at idle but maybe even lower because when I was out last night with it it would shut off by itself while at a stop sign or red light. the CEL is on but I think the position of the distributor may be off a bit, could that be the low ilde issue? thanks in advance.
