1g head swap with unusual codes

[projoe86]

I just put a 1g head on my 96 gsx and now got some odd codes coming up. Here's what is happening. My car is running extremely rich and won't run much more than 60mph. My coolant fans always run too. my codes that come up are po100, po105,po110,po115. The codes for the bad MAF and coolant temp sensor still come up even though I replaced them both. My map sensor code was expected. I have talked to a few people that have done the swap and no one has had the problem with the MAF. I checked my wires for any damage and found none. I tested them for power and all was good. I even called up a shop called up slowboy racing and none of their mechanics know what to do about it. I really hope there's some one out here that can help. If you need any more info just let me know and I'll tell you all that I can.
Thanks,
A very frustrated dsm owner

well found out that my ecu is the root of my problems. So hopefully I'll be back in action soon.
