Chevy Impala Stalling Issues: Diagnosing C1226, C1245, U1000, PO102, P0350, P0420, P0455, P1350 Fault Codes

Model: Chevy Impala Fault Code: C1226 Posted: 2019-07-04 00:01

I've been experiencing repeated stalling issues with my Chevrolet Impala. The car runs smoothly under normal conditions but will suddenly shut off when I stop at a traffic light or slow down. It typically restarts immediately after. In some cases, the vehicle stalls even when idling from a complete stop. I've checked the onboard diagnostics and found several fault codes: C1226, C1245, U1000, PO102, P0350, P0420, P0455, and P1350. These codes are indicating potential problems with the ignition control system, fuel delivery, and engine performance. I'm seeking advice on how to properly diagnose and resolve these issues to prevent further stalling events.

Begin troubleshooting with fault code P1350, which points to the Ignition Control System. Refer to BBBind.com for detailed wiring diagrams and verify power supply and ground connections to ensure proper electrical integrity.

Thank you for the guidance—I'll review the P135s0 code and check the wiring diagrams on BBBind.com to confirm grounding and power connections.
