Diagnostics & Repair

Check engine lights, misfires, boost leaks, electrical gremlins and noises, diagnosed with factory-level tools and fixed right.

Overview

How we approach diagnostics

A code is a starting point, not a diagnosis. Our technicians use factory-level scan tools, smoke machines, oscilloscopes and datalogging to find the actual cause, whether it is a boost leak on a WRX, a failing cam sensor on a 2JZ or a corroded ground on a 30-year-old 240SX.

You get a clear explanation, a photo or datalog of the fault, and a written estimate before any repair begins.

What is included

  • Factory-level scan tools for every Japanese make we serve
  • Boost-leak, smoke and electrical testing
  • Written estimate and evidence before repair
