Hi,
I have a 2001 volvo s40.
I have6 check engine light codes that came on. They were duplicated. PO128, PO130, and PO107. I am not sure what to fix. Could it be that all three things are bad or is one thing tripping all the other codes. Has anyone have this happen to them.

The issue that I have been having is that my car sometimes won't start. It is usually the first thing in the morning. Once it starts I don't have any problems anymore for the rest of the day.

Any advice out there?

 

P0128 infamous low coolant. Start with new thermostat ($10), then if didn't fix try thermo sender ($50).
P0130 O2 circuit (Bank1, Sensor 1)
P0107 Manifold absolute pressure/BARO Sensor low input
