The client challenge

What we walked into.

A stubborn check-engine light and an occasional stumble at idle. Two previous shops had replaced spark plugs, coils, and the mass air flow sensor — with no change and a five-figure bill.

  • Recurring fault with no clear cause
  • Parts replaced 'in case' rather than by diagnosis
  • Warranty on prior work already exhausted
  • Client considering trading the car in
Our solution

How we put it right.

We connected the RX to factory-grade diagnostic equipment, pulled live data from every module, and traced the fault to its true source in under an hour.

Multi-module scan

Engine, transmission, ABS, SRS and body modules all inspected for stored and pending codes.

Live data capture

Fuel trims, O2 sensor voltages, and misfire counters logged under load.

Real root cause

A cracked intake manifold gasket causing an intermittent lean condition.

One-part fix

Single OEM gasket replacement — no unnecessary hardware.
