DME replacement? ADVICE

My car has coded out 30BB. Misfires on cylinders 4-6. 30BB is the code for DME internal failure. I am running a JB4, BMS DCI, and catless downpipes. Has anyone dealt with this? What are some easy steps to try and see if it is not something else that would be tripping this code. I have been trying to get an FI on it to really nail down exactly what is going wrong but havent been successful. As of right now I don't possess the funds to replace a DME and go through all of that.

I have read this :
