Engine Repair & Diagnostics

Check Engine Light On? Here's What To Do.

The check engine light is your car's way of telling you something is wrong. While it can be stressful, ignoring it can lead to more expensive repairs down the road. At American Auto Repair NJ, we use factory-level diagnostic equipment to read the specific trouble codes and, more importantly, interpret them correctly.

Comprehensive Engine Services

From routine maintenance to major overhauls, our team handles it all:

• Computer Diagnostics: pinpointing sensor failures, vacuum leaks, and electrical issues.
• Timing Belts & Chains: Preventing catastrophic engine failure with timely replacements.
• Head Gaskets: Expert repair for overheating engines and coolant leaks.
• Tune-Ups: Spark plugs, ignition coils, and filters to restore power and fuel economy.

Signs of Engine Trouble

Beyond the warning light, look out for:

1. Rough Idling or Stalling

If your car feels shaky at stoplights or stalls unexpectedly, it could indicate fuel delivery or ignition problems.

2. Poor Fuel Economy

A sudden drop in MPG often points to oxygen sensor issues, dirty air filters, or fuel system inefficiencies.

3. Unusual Noises

Knocking, clicking, or hissing sounds from the engine bay should never be ignored.
