Professional Engine Diagnostic Services
A few weeks back, a customer pulled into our shop on 1 Upland Avenue with a check engine light that another shop wanted to charge him for replacing his catalytic converter. He needed honest engine diagnostics in Upland, PA before dropping that kind of money. Turns out, he just had a loose gas cap and a bad oxygen sensor. After almost 40 years serving Delaware County, we see this story play out all the time.

Complete Engine Diagnostic Services
From basic check engine light scans to deep computer system analysis, S&S Automotive Service handles every type of engine problem. Our experienced mechanic uses professional diagnostic equipment to pinpoint exactly what's wrong with your engine, so you only pay for the repairs you actually need.
Check Engine Light Diagnosis
That little orange light causes a lot of stress for Upland drivers, but it doesn't always mean something serious. We hook your vehicle up to professional diagnostic scanners that read trouble codes from your engine's computer. Then we explain in plain language what those codes actually mean for your car.
Common reasons your check engine light comes on:
- Loose or faulty gas cap
- Failing oxygen sensor
- Bad spark plugs or ignition coils
- Catalytic converter problems
- Mass airflow sensor issues
Most check engine light scans take about an hour, but complex issues sometimes take longer to track down. We never start repairs without explaining the problem first.
OBD-II Scanning and Code Reading
Every car built after 1996 has an OBD-II computer system that tracks how your engine performs. Our shop uses advanced scan tools that go beyond basic code readers, pulling live data, freeze frame information, and manufacturer-specific codes that cheap scanners miss.
We don't just read codes and guess. We test components, check sensor data, and verify the actual problem before recommending any repair. This saves Delaware County drivers hundreds of dollars compared to shops that replace parts based on codes alone. We provide diagnostic services for all vehicle makes and models, from older domestic vehicles to modern imports.
Engine Performance Testing
Sometimes your engine feels off even when no warning lights show up. Maybe it hesitates at stoplights on Chester Pike, lacks power going up the hills toward Media, or burns more gas than it used to. These problems need real testing, not just code scanning.
Our engine performance testing includes:
- Compression and leak-down testing
- Fuel system pressure checks
- Ignition system analysis
- Vacuum and intake testing
- Electrical diagnostic work when sensors or wiring are involved
Misfire Diagnosis and Repair
A misfiring engine shakes, runs rough, and wastes fuel. You might feel it most at idle or when accelerating from a stop. Misfires also damage your catalytic converter over time, turning a small repair into a big bill if ignored.
We track down misfires by testing each cylinder, checking spark plugs and coils, measuring fuel injector performance, and looking at compression numbers. Most misfire repairs cost far less than people expect, especially when caught early.
Emissions Failure Diagnostics
Failed your PA state emissions test? We diagnose emissions problems and get your vehicle ready to pass. Our shop handles everything from oxygen sensor replacement to EVAP system repairs, and we can usually fix emissions failures the same week. Pair this with our state inspection and emissions services for a smooth retest process.

Engine Diagnostic Questions from Our Customers
After almost 40 years of engine diagnostic work in Delaware County, we hear the same questions from concerned drivers every week. Here are honest answers to the engine concerns that worry Upland residents most.
What does it mean when my check engine light comes on?
A check engine light means your vehicle's computer detected a problem somewhere in the engine, emissions, or related systems. The light could mean something minor like a loose gas cap, or something serious like a failing catalytic converter. A solid light usually means a non-emergency problem you should address soon, while a flashing light means stop driving and get help right away because continued driving could cause major engine damage. The only way to know for sure is to have the codes scanned and properly diagnosed by a qualified mechanic.
How long does engine diagnostic testing take?
Basic code scanning takes about an hour, but full diagnostic testing depends on what's wrong with your vehicle. Simple issues like a loose gas cap or bad oxygen sensor can be diagnosed quickly, while intermittent problems or complex computer issues might take several hours to track down. We always give you a time estimate before starting, and we call before doing any repair work. Rushing diagnostics leads to wrong answers and wasted money, so we take whatever time the job actually needs.
How much should I expect to pay for engine diagnostics?
Engine diagnostic costs vary based on how complex the problem is and how much testing your vehicle needs. A basic check engine light scan costs less than full diagnostic testing for hard-to-find issues. Some problems show up immediately on a scan tool, while others require additional testing of sensors, fuel systems, or electrical components. We provide honest estimates before starting any diagnostic work, and the diagnostic fee often gets applied toward your repair if you have us fix the problem.
Can I drive with my check engine light on?
A solid check engine light usually means you can drive safely for a short time, but you should get the problem diagnosed within a few days. Driving too long with the light on can turn small problems into expensive repairs, especially if it's an emissions issue that damages your catalytic converter. However, if the light is flashing, stop driving as soon as it's safe and call us at 610-876-6494. A flashing light means active engine misfire that can destroy expensive parts within minutes. When in doubt, call us and describe what you're feeling from the vehicle and we'll tell you whether to drive in or arrange a tow.
