Drivability Problems
How Your Engine Is Telling You Something's Off
If any of these sound familiar, the engine is talking. We translate.
Engine Misfire
Usually a bad coil, plug, injector, or compression issue. We pull codes and test cylinders to confirm.
Rough Idle
Vacuum leak, dirty throttle body, failing sensor, or misfire. Often a fast fix once we identify it.
Loss of Power
Could be ignition, fuel, exhaust, or sensor-related. We diagnose live data and pinpoint the issue.
Poor Fuel Economy
Often O2 sensor, MAF sensor, dragging brakes, or a misfire. We check what's actually affecting it.
Car Overheating
Thermostat, water pump, radiator, or fan issue. We diagnose cooling on-site.
Check Engine Light
We pull the code, but more importantly — we test the circuit. The code points; it doesn't always answer.
A code reader points at a problem. It doesn't always answer one. P0420 isn't always a catalytic converter. P0300 isn't always plugs. We test the system before we replace anything.

Common Questions
Engine Performance FAQ
Can you fix a misfire on-site?
Usually yes — most misfires come down to plugs, coils, or injectors, all of which we replace on-site.
Do you do tune-ups?
Yes. Plugs, filters, and a full performance inspection. We'll tell you what else needs attention while we're under the hood.
Can you replace sensors at my house?
Yes — O2 sensors, MAF, MAP, crank, cam, knock — almost all sensor replacements happen on-site.
What if it's an internal engine issue?
If the job needs a lift, special tooling, or full teardown, we'll tell you up front and recommend a path forward.
How long does a tune-up take?
Most tune-ups are 1 to 2 hours depending on the vehicle.
