Stop guessing. We identify the actual cause so you fix the right thing the first time.

Diagnostics & Check Engine

Modern vehicles throw a lot of codes. We combine professional-grade scan tools with live data, component testing, and real-world experience to separate symptoms from root causes—saving you time and money.

What we check

  • Computer scan: stored/active codes, freeze-frame data, readiness monitors
  • Electrical testing: battery/charging, grounds, voltage drops, continuity
  • Sensor & actuator checks: MAF, O₂/AFR, MAP, EGR, EVAP, VVT, misfire diagnosis
  • Fuel/air & mechanical basics: vacuum leaks, fuel pressure, compression, timing
  • Road test with data logging to verify under load

Clear explanation of findings, recommended repair options, and an estimate. If work proceeds with us, the diagnostic fee is often applied toward the repair (ask for details).

Deliverable

Common symptoms we solve

Hard starts, stalling, misfires, poor MPG, rough idle, failed emissions/inspection, intermittent lights.

FAQs

  • Can you clear my light? We can, but clearing without repair won’t solve the problem and may hide useful data.
  • My light is flashing—what now? A flashing MIL indicates an active misfire. Stop driving and call us to prevent damage to the catalytic converter.
