Hi!

I have a 2001 Bonneville that has been giving me a P0401 code that has kept me from passing an emissions test. The erg and the map sensor were replaced last year, the throttle body assembly was replaced or cleaned last year. I tried taking off the pipe that goes from the erg to the manifold and cleaned it out with carburetor cleaner and put it back on. Then my code reader showed a P0102 code and the car won't start now. If I unplug the maf it runs. I got a new maf and it is the same problem.

Any advice on how to fix this would be greatly appreciated.
