<![CDATA[CEL after d16y8 motor swap... can't pull a code...]]>Hey guys quick question. Over the weekend we put a d16y8 into my 92 hatch. The motor starts and runs pretty well. However, I have a check engine light haunting me. The check engine light won't come on until the car has been running for like 5-10 seconds, and if I try to pull the code it just stays solid. One thing you should know if I'm running open header until I get my exhaust done on monday. Would that be why, or what else can I check?

You cant just turn the key and pull the code, you need jump the wires togethjer to put it in limp mode. I put a toggle switch for those 2 wires right above the ECU, just flip the switch and the light will stay on solid then flash the codes.

If you cant pull the code there is none to be pulled esp if the light turns itself off.

I think it's the 4 wire tufte, but I'll have to check.
