TROUBLESHOOTING
A "Check Engine" light can mean anything from a loose gas cap to a critical timing issue. At GC Automotive & Performance , we go beyond simple code-pulling. We use dealership-level scanning tools and real-time data logging to pinpoint the exact failure, saving you time and preventing the "parts cannon" approach to repairs.
Check Engine Light
We pull deep-level codes and perform circuit testing to find the root cause of your dash warnings.
Drivability Issues
Experiencing stutters, stalls, or rough idling? We analyze fuel trim and spark health to smooth it out.
Electrical Testing
From parasitic battery drains to faulty sensors, we trace wiring issues that others might miss.
Emissions Failures
Failing your NJ state inspection? We diagnose EVAP systems and catalytic efficiency to get you passing.
Performance Logs
For performance builds, we monitor boost, air-fuel ratios, and timing to ensure your engine is safe.
No-Start Diagnosis
If your car won't turn over, we check the starter, alternator, and security system to get you moving.
