Real Answers. Better Repairs. Engine Diagnostics & Repair in Mertztown, PA

At E-Motive Performance & Auto Repair, we’re not just fixing engines, we’re fixing how engine repair is done. We started this shop to revolutionize auto repair by delivering faster service, transparent diagnostics, and repairs that make sense for real drivers. Whether you’re dealing with a check engine light, a strange noise, or a major engine failure, we help you understand exactly what’s going on without scare tactics or pressure.

Our process is built on accuracy, not assumptions. We use advanced scan tools from Snap-on and Autel and real-world testing to pinpoint the issue, explain it clearly, and recommend the right fix. From minor repairs to top-half engine rebuilds and full replacements, we work on most makes and models, treating every vehicle with the same care and honesty we’d want for our own.

What We Do During Engine Diagnostics

Engine problems can feel overwhelming, but we make the process simple and transparent. When you bring your vehicle in, our team performs a comprehensive diagnostic that goes far beyond just pulling a code.

Check Engine Light Diagnostics

A check engine light doesn’t always mean disaster, but it does mean something needs attention. We scan for trouble codes, but more importantly, we interpret what those codes mean. Our diagnostics include system testing, visual inspections, and pinpoint analysis to identify the root cause, not just clear the light.

Engine Performance Troubleshooting

If your vehicle is running rough, stalling, hesitating, or losing power, we dig deeper. We evaluate sensors, ignition timing, fuel delivery, compression, and airflow to determine what’s affecting performance. Whether it’s a faulty coil, clogged injector, or sensor failure, we’ll find it and fix it right.

Honest, High-Quality Engine Repairs

Once we know the cause, we recommend a repair plan that fits your vehicle and your goals. We focus on OE or equivalent parts, skilled workmanship, and clear communication—so you know what’s being done and why.

Sensor & Electrical Repairs

Modern engines rely on dozens of sensors and modules. If a sensor fails or sends inaccurate signals, it can trigger warning lights or reduce performance. We repair and replace sensors with precision and verify results with post-repair testing.

Gasket, Seal & Valve Cover Repairs

Oil leaks, coolant issues, and pressure loss often come down to worn gaskets or seals. We repair common failures like valve cover gaskets, intake manifold gaskets, and more using high-quality materials and proper prep to prevent future problems.

Camshaft & Top-End Rebuilds

We perform top-half engine rebuilds, including camshaft replacements, lifters, rockers, and timing components. These repairs are especially common in vehicles with higher mileage, ticking noises, or loss of power. We rebuild with precision and back our work with solid warranty coverage.

Engine Replacements

When repair costs outweigh the value of your engine, we offer complete replacement options using new, used, or remanufactured engines based on your budget and vehicle. We’ll walk you through your choices and handle the job with professionalism and care—no surprises, no shortcuts.

Common Signs Your Engine Needs Attention

Engine issues don’t always start with a light. If you notice any of these symptoms, schedule a diagnostic before it turns into a bigger problem:

Rough idling or shaking
Your engine should run smoothly and steadily; shaking at stoplights or inconsistent idling could indicate ignition or fuel issues.
Loss of power or acceleration
Struggling to accelerate or feeling sluggish on hills can point to sensor problems, compression loss, or fuel delivery issues.
Engine knocking or ticking sounds
Unusual noises may be a sign of low oil, worn components, or internal damage that shouldn’t be ignored.
Unusual exhaust smoke (blue, white, or black)
Each color points to a different problem, like oil burning (blue), coolant leaks (white), or fuel mixture issues (black).
Oil or coolant leaks under the vehicle
Puddles or spots in your driveway can signal failing gaskets or seals—something small that can become serious.
Strong fuel or burning smell
A lingering fuel odor or burning scent might mean a leak, faulty injector, or electrical problem.
Reduced fuel economy
If your MPG drops unexpectedly, your engine may not be running efficiently due to a sensor, plug, or air/fuel issue.
Dashboard warning lights (check engine, oil pressure, temperature)
Warning lights are your car’s way of asking for help, especially if flashing or combined with performance issues.
