Engine Diagnostics
Find out what your engine is telling you
When your engine runs rough, loses power, or lights up the dashboard, it’s trying to tell you something. The challenge is reading those signals correctly — a misfire, a rough idle, or a check engine light can each have several possible causes.
We go beyond pulling a code. Our technicians test the engine’s actual performance — fuel, ignition, air, compression, and sensor data — to find the true cause of the problem, so the right repair gets done the first time instead of throwing parts at it.
What our engine diagnostics cover
Check Engine Light
We trace check engine lights to the real cause instead of guessing from the code alone.
Misfires & Rough Running
Diagnosing misfires, rough idle, stalling, and hesitation down to the cylinder and component.
Performance & Power Loss
Finding the cause of lost power, poor fuel economy, and engines that just don't feel right.
Live Data & Testing
Reading live sensor data, fuel, ignition, and compression to confirm the fault before we repair it.
When you might need engine diagnostics
- Check engine light is on or flashing
- Engine idles rough or stalls
- Misfiring, hesitation, or surging
- Noticeable loss of power
- Drop in fuel economy
- Unusual engine noises or smells
