I will get one but the problem is since I had the ECU repaired there are no codes and the car won't stay running long enough to trip any.

I am going bald from pulling my hair out with this car. I have a 2004 S-80 2.9 Liter L6 Non-Turbo. Its started with running really weakly. My son got stranded on the highway because the car would not do over 20 MPH and even with your foot on the floor the RPM's would not go over 2000. We got it home...

Do you think replacing the ECM will solve that issue?

The code is P0105

Its the 2.9 Liter L6 Non-Turbo.

Can anyone help me, please? I have a 2004 S80, Non-Turbo model that is not running well at all. When it starts it is either rough to start or when it starts is has a rough idle. When you step on the accelerator the RPM's will not go over 2000. I ran a code reader and I get a P0105 code that says it ...
