A Check Engine Light Is Your Car Talking
That light covers hundreds of possible issues. The code only points to a system — finding the actual fault takes real diagnosis.

A code like 'System Too Lean' could mean a vacuum leak, bad sensor, or failing fuel pump. We read live sensor data to pinpoint the true cause — so you fix it once.
