Someone please help save me money!

Here is the problem, I have a 94 Honda Civic!!
Na really though my check engine lamp is on. i have used the paper clip method to find out that it is a code 6 which happens to be coolant temp sensor. I have replaced the ecu (phearable.net) and all 3 coolant system sensors and have yet to find the problem.

Along with the light on is the lack of power! after the car heats up (normal operating temp) it loses all of the little bit of power it has (sohc!)

Anyone out there with any ideas please let me know! Thanks
