Hi David my name is Jason.

What scan tool are you using?

Customer: replied 1 year ago.
Hi Jason, I'm not sure as it isn't my scanner. I can find out if needed. The engine just runs in limp mode, max @2100 rpm under a load, however will rev free-wheeling.

Are you working on this yourself, or is a mechanic working on this and relaying you information?

Customer: replied 1 year ago.
I had a mechanic come by and he pulled the code. He is a bit mystified at this point.
Expert:  Jason replied 1 year ago.

Can you find out what tool he is using, and specifically what the code says?

Customer: replied 1 year ago.
Ok found out the code. Code 41 Shows fault H, G, D, B, A.
