I put a D15Z1 in my 95 Del Sol with the ECU and D16Z6 head that came in the car. It fired right up and seems to run good but the CEL is on. I flashed the codes by using a jumper and it has one long flash followed by eight short flashes. I'd say that is 18 but there is not an 18 listed????? I did have a broken wire on the top plug on the passenger fender but I fixed that. What do you guys think?
