Mobile Check Engine Light Diagnostics
A code reader tells you where to look. It doesn't tell you what's broken. A P0171 "system too lean" code, for example, can come from a vacuum leak, a dirty MAF sensor, a weak fuel pump, or a cracked intake boot, and each fix costs something very different.
Walter brings the scan tool to your driveway or parking lot, reads the codes and live data, and then does the actual troubleshooting: checking connectors, testing sensors, looking for leaks. You get a plain-English explanation of what's wrong and what it will cost before you spend anything on parts.
What's included
- Full code scan, including pending and history codes where your vehicle supports them
- Live data review (fuel trims, sensor readings, misfire counts)
- Visual inspection of wiring, connectors, hoses and vacuum lines related to the code
- A clear explanation of the likely cause and what Walter recommends
- An upfront quote for the repair, whether that's done on the spot or scheduled
Signs you need it
- The check engine light is on steady
- The light is flashing (usually an active misfire; drive as little as possible)
- Rough idle, hesitation, or loss of power
- Worse fuel mileage than usual
- A failed emissions/state inspection
- A smell of fuel or rotten eggs

Walter comes to you
Home, office, or parking lot in Fort Bend County.
Most diagnostics happen right where the car is parked. Walter needs a safe, legal spot to work, access to the vehicle and keys, and ideally a few minutes to talk with you about when the problem shows up (cold start, highway speeds, after rain, etc.). If the problem turns out to need a lift or a shop, he'll tell you that up front.
Why Walter
Walter Curo learned the trade as a U.S. Army mechanic, serving four years and maintaining more than 200 vehicles and pieces of equipment. He later spent years in dealership collision repair and worked as an insurance auto damage adjuster. He explains what's wrong in plain English and gives you the price first. More about Walter.
Frequently Asked Questions
Is it safe to keep driving with the check engine light on?
If the light is steady and the car drives normally, it's usually OK to drive gently until it's checked. If it's flashing, or the car is running rough, overheating or losing power, stop driving it and call. A flashing light often means a misfire that can damage the catalytic converter.
Can't I just get the code read for free at a parts store?
You can, and it's a fine first step. But a code is a starting point, not a diagnosis. Walter tests the parts behind the code so you're not replacing sensors on a guess.
Will clearing the code fix the problem?
No. Clearing a code just turns the light off until the computer sees the fault again. It also erases readiness data you need to pass inspection.
How much does diagnostics cost?
Call or text with your vehicle and symptoms, and Walter will tell you the price before he starts.
