Check the listing for details. 2008-2009 Impala ECM 12630457 | Programmed to Your VIN | Engine Computer. Condition: Remanufactured, Made in United States. Listed at 118.99 USD. On a hunch, I monitored the ECM data stream while using a heat gun to gently warm the module. Sure enough, as the ECM temperature rose, the injector pulse width data started fluctuating wildly just before it stalled.
