Now I'm getting a p108 code and the engine dies after a couple minutes. I no what it means but could I have done anything to cause it? Could it be a vac line behind the dash pinched or routed wrong? I know there's a lot of air in the cooling system, could that effect it? It doesnt run long enough to let me bleed the system. I only have about 2 gallons of coolant in and its not taking mor yet. Anyone have any ideas?

Found this link hope it helps. P0108 Manifold Absolute Pressure/Barometric Pressure Circuit High Input

Thanks. I had actually read that one. It gave me the idea of a messed up vac line behind the dash since its all connected. I'm just not sure if that's a possibility or not. I don't really think it's a bad map sensor, but I'll check it to make sure. I don't think my idea of the low coolant effecting it is possible so I'll scratch that off the list.

Thanks for posting the info and I'll follow the instructions to test the map.

Totally separate issue.Vacuum leak like a the small hose for the HVAC will not cause this issue.


In most cases from my experience has been a bad MAP sensor that causes P0108.

Ok. Thanks. It's just weird that it was on after I hooked the battery up and started it to bleed the system.
