Check engine light on? Get an answer, not a guess.
A code tells you where to start looking — not what to replace. Our $150 flat-rate diagnosis tests down to the actual cause, and includes a full health & safety inspection of the whole vehicle.
Why it's worth it
A real diagnosis beats throwing parts at the problem.
Here's the trap: a free code scan says “O2 sensor,” so you buy an O2 sensor. But that code can be triggered by wiring, a vacuum leak, an exhaust leak, or a fuel problem. The new sensor doesn't fix it, and now you're $200 in with the light still on.
Diagnosis is testing, not scanning. We follow the code to the circuit, test the components involved, and confirm the actual cause before recommending anything. Then you get findings by call or text with priced options — before any repair work starts.
It covers more than warning lights: no-starts, stalling, misfires, strange noises, leaks, poor fuel economy, and anything that just doesn't feel right on the road between Rexburg and Idaho Falls.
When to book it
Book a diagnosis when your vehicle does this.
- Check engine light on — steady or flashing (flashing means get it looked at right away).
- Won't start, or starts only sometimes.
- Stalling, rough idle, or misfiring.
- A new noise — clunk, whine, tick, or grind you haven't heard before.
- Fluid dripping where you park.
- Running hot, running rough, or fuel mileage falling off.
What it costs
One flat rate. Inspection included.
Nothing wrong yet?
If you just want an honest once-over rather than chasing a specific problem, the $45 visual multi-point inspection is the right fit.

FAQ
Diagnostic questions, answered straight.
My check engine light is flashing. What do I do?
Ease off and get it checked as soon as possible. A flashing light usually means an active misfire, and driving on it can overheat and ruin the catalytic converter — turning a spark plug problem into a four-figure repair. Call us at (208) 842-3535.
The parts store scanned my code for free. Why pay $150?
The free scan gives you a code — a starting point. The $150 buys the testing that finds the actual cause, so you fix the right thing once. It's almost always cheaper than replacing parts that don't fix the problem.
What exactly do I get for $150?
A tested answer for what's wrong, a full health & safety inspection of the whole vehicle, and a call or text walking you through findings with priced options. You decide what happens next — no pressure either way.
How long does a diagnosis take?
Plan on at least 5 hours with the vehicle at the shop — a full-day drop-off is ideal. Good testing takes time, and we'd rather get you the right answer than a fast guess.
