have you done any upgrades lately. new cai, new performance air filter

p1101 is actual measured airflow to maf,map, egr and tp is not with in calculated airflow range.

any change in airflow might cause this the 1101 points more towards maf.

try disc battery for 10 minutes that should clear codes and see if they come back in.
Some cadillac will throw this code when cat was replaced. Does not cost anything just some time.

Cleared a couple times. Never lights up dash, just saved in PCM and takes about 5-10 mins to set. Dod manifold gasket was recently replaced I just found out and boss said to pull it off and check for a fuck up. Everything looks good, but noticed a small exhaust leak from when cat was welded on. Size of small spot weld. Think that could be the problem?
