Well, my trouble codes are coming in 3s now. I have a code 2,15, and 17. I will change out the o2 sensor b/c of the code 2. I think the other two codes are due to the o2 sensor.

I bought some Lubro Moly Venti Sauber and Fuel Injection cleaner. Will try that out also.

Where is this engine harness that everyone is talking about on a 400e?
