Diagnosing Your Check Engine Light for a Quick Fix

A check engine light signals potential problems that require immediate attention. Delaying diagnostics increases the risk of serious damage. Engine performance, fuel efficiency, and emissions depend on properly working components. A simple issue like a loose gas cap or a major failure like a faulty sensor could trigger the warning light. Every illuminated light requires a thorough diagnostic check to pinpoint the cause. At Leighton's AutoWorx, we provide expert check engine light diagnostics for clients in Hampstead, New Hampshire.

We go beyond a basic scan to determine the real cause of the issue. Our service provides clear explanations so you understand what needs to be fixed.

Our Check Engine Light Diagnostics Services

Advanced Computer Diagnostics

Every modern vehicle uses an onboard diagnostic system to monitor performance. Our service includes a full scan of stored error codes to identify faults. A deep analysis of engine, transmission, and emissions data helps locate the problem. Checking live sensor readings provides a complete picture of system performance.

Emissions System Testing

A faulty oxygen sensor, clogged catalytic converter, or malfunctioning EGR valve triggers the check engine light. Our service identifies emissions-related issues that affect efficiency. A properly working emissions system improves fuel economy and meets environmental standards. We detect and fix these problems to reduce harmful exhaust gases.

Ignition System Inspection

Faulty spark plugs, failing ignition coils, or sensor malfunctions cause misfires. Misfiring leads to poor acceleration and increased fuel consumption. We conduct detailed inspections of ignition components to detect early signs of wear. Replacing damaged parts restores smooth engine operation and prevents further issues.

Fuel System Analysis

A clogged fuel injector, weak pump, or failing sensor can affect performance. If a vehicle struggles to start, stalls, or runs roughly, it may have fuel system issues. Our professionals check pressure, injector function, and fuel delivery efficiency, fixing these problems to enhance reliability and prevent costly damage.

What our customers say

A row of black stars on a white background.

My husband’s car needed an oil change ASAP. I called several garages in the area, and most couldn’t do it w/o an appointment. When I called Leighton’s, they gave me a time frame that would work for them, and I showed up. :) They moved quickly and efficiently. I couldn’t have been happier with the way they treated me and the car. First class service!

Barack is, without a doubt, the best mechanic in the area. He always finds time to fit you in , in a timely fashion. He will never sell you or tell you need something if you don’t. I have the utmost trust in Barack and would never bring my car to anyone else. His pricing is excellent and he’s the best. What more can you ask for? I highly recommend him. You will not be disappointed.
