Ignition coils

We replace failed coils, and tell you if the others are near the end of their life too.

Spark plugs

We install the correct plugs, gapped and torqued to spec, which is important on aluminum heads.

Verify the fix

We clear the codes and test-drive to confirm the misfire is gone.

When a shop is the better choice

Ignition Coil & Spark Plug Replacement in Garland: questions

Is it safe to drive with a flashing check engine light?

Drive as little as possible. A flashing light usually means a misfire is sending unburned fuel into the catalytic converter, which can overheat and destroy it.

Coil or spark plug: which is bad?

We can swap the coil to another cylinder and see if the misfire follows it. That tells us whether the coil or the plug is the problem.

Can you replace spark plugs at my home in Garland?

Yes. Coils and plugs are well suited to mobile service in your Garland driveway or work lot.
