Summary
13102 - Emission Recall - IMPCO Automotive Recall (Not a GM recall - Administering recall for IMPCO). Vehicles were built with an incorrect ECM calibration that, under some conditions, may cause higher tailpipe exhaust emissions than allowed by the applicable emission standards. Dealers will reprogram the engine control module (ECM). The change to the catalyst temperature model will allow the vehicle to operate as originally designed.
