As much as I would love to I can't live on the internet. I am just waking up for the day. If you would like to continue please let me know.

Your problem is goin to be under the valve covers. The rough running if not caused y the IDM module itself is defective wiring. Over the years the under valve cover harnesses wiggle loose and get oil in the connections. This causing changes in the resistances that cause the vehicle to run rough. Same goes for the IC sensor. If there is oil in the connection both the connector and ICP sensor need to be changed. You don't just want to change the under valve harnesses on one side I would highly recommend replacing them both to ensure all 8 cylinders are firing correctly.

poor website never really got a good answer, its been over 24 hours I would request a refund and cancel my membership

I just gave you an answer 2 hours ago. There is no instant answer in diagnosing a vehicle I don't have a magic wand. Tat is why I asked if had codes and you give me a simple no as your answer. Then when I do reply while i'm in bed and get upset because you don't have patience. I gave you an answer on how to repair your vehicle so Yes I did give you an accurate answer. I have fixed these vehicles from day one.
