🚦 1. Trouble Codes & Symptoms

These are common codes related to the fuel system or oxygen sensors:

P0420: Catalyst efficiency below threshold
P0171: System too lean
P0138: O2 sensor voltage high

They often indicate a worn oxygen sensor, exhaust leak, or ignition issue.

If you’re not sure, simply tell us your year, make, model, and engine—we’ll check the exact part you need.

It’s very possible. Common symptoms of a failing ignition coil include:

Rough idle or shaking
Hard cold starts
Poor acceleration
Higher fuel consumption
Misfire popping noise

Tell us your vehicle info—our team can help you identify the cause.

Typical signs include:

Check Engine Light on
Increased fuel consumption
Poor acceleration
Strong fuel smell
Slow throttle response

Most sensors should be replaced every 80,000–100,000 km.

🔍 2. Fitment & Compatibility

Just provide:

Year
Make
Model
Engine size

We’ll confirm:

Upstream or downstream
Correct connector
Proper OEM reference number
Federal vs. California emissions compatibility

OEM: Same quality as the factory part; long-lasting
High-quality aftermarket: Close to OEM but more affordable
Cheap low-end coils (we don’t sell these): Short lifespan, unstable performance

We only offer high-grade, reliable ignition coils.

Most vehicles have 2–4 sensors:

Upstream (front): Controls air–fuel ratio
Downstream (rear): Monitors catalytic converter performance

We can confirm the exact number for your vehicle.

🛒 3. Buying, Quality & Concerns

Yes, temporarily.

The ECU needs a few miles to adjust new injector values.

It should stabilize after driving a short distance.

High-quality heating elements
Durable housings
Precise signal response
