Bringing back a dead thread.
I have a 2014 GT/CS I had the VMP Stage 3 Supercharger kit installed. The only exhaust mod is an axleback system. After about 1500-2000 miles it started getting colder (50's)and I threw the CEL P219a code, Cleared it and had no issues. But it popped up gain lastnight (37 degrees and Rain) wasn't running weird at all, Justins said its usually a header or x pipe leak, I have neither. Any Ideas???
