This 2007 Jeep Liberty came in for diagnostic due to Check Engine Light after a DIY did not fix it
September 22, 2026
It was severely underperforming. As the car would not stay running & kept shutting off.
Inspection Findings: Check engine light on for o2 sensors and misfires. We popped the hood and found cheap amazon ignition coil, no name spark plugs & o2 sensors.
We Evicted the failed parts because they weren't paying the bills. After installing some quality name brand ignition coils, NGK Spark Plugs & NTK oxygen sensor. The engine performance came back.
