Anyone else have this problem
Their was several ecu updates for early model cars related to idle stability especially with A\C cycling

2103 manual latest ecu calid is likely to be ZA1JB01C, you car may have come with A01C or B00C

as other guy said aftermarket intakes can upset maf calobration and cause issues.
