I have a 2007 impala ss with a 5.3l and displacement on demand. Just noticed I have a dtc of p1101. Has anyone every had this before??? Please help I can't find any info on it and its driving me crazy!!!! Thank you in advance.
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?
