Our Comprehensive Diagnostic Process
Step 1: Customer Interview
We start by listening. When does the problem occur? What symptoms do you notice? Your observations help us focus our testing.
Step 2: Computer Scan & Code Analysis
We connect professional diagnostic equipment to retrieve:
- Current and stored trouble codes
- Freeze frame data (conditions when codes were set)
- Live sensor data and readings
- System status and readiness monitors
Step 3: Visual Inspection
Many problems have visible causes. We check:
- Wiring and connectors for damage or corrosion
- Vacuum lines for cracks or disconnections
- Fluid levels and conditions
- Belts and hoses for wear
- Air intake for restrictions
Step 4: Component Testing
Using specialized equipment, we verify component function:
- Oscilloscope analysis – verify sensor signal patterns
- Fuel system testing – pressure, volume, and injector operation
- Ignition testing – spark strength and timing
- Compression and leak-down tests – engine mechanical condition
- Electrical testing – circuits, grounds, and power supply
- Smoke testing – find vacuum and EVAP leaks
Step 5: Diagnosis & Explanation
We explain exactly what we found in plain English. We'll show you the problem when possible and provide a detailed written estimate before any repairs.

Frequently Asked Questions
How much does a diagnostic test cost?
Diagnostic fees vary based on complexity, typically ranging from $75-$150. The fee covers our time and expertise to properly identify the problem. If you authorize repairs, the diagnostic fee often applies toward the repair cost.
Why can't you just tell me what's wrong over the phone?
Symptoms can have many causes. A "rough idle" could be caused by 50+ different problems. Proper diagnosis requires hands-on testing with specialized equipment. Guessing wastes your money on parts that may not fix the issue.
Can I bring my own parts?
We prefer to source parts ourselves to ensure quality and provide warranty coverage. Customer-supplied parts cannot be warrantied, and incorrect parts can cause additional problems.
How long does a tune-up take?
Basic tune-ups typically take 1-2 hours. More comprehensive services involving fuel system cleaning or multiple component replacements may take 2-4 hours.
