Introduction

Like most modern cars, each cylinder has its own ignition coil rather than sharing one via a distributor as in the past. All four are identical, so troubleshooting can be as simple as swapping coils and seeing if the issue follows the coil.

What you need

Using a 10 mm socket, remove the bolt securing the #4 coil.
For reassembly, the tightening torque is 9.8 ~ 11.8 Nm (1.0 ~ 1.2 kgf.m, 7.2 ~ 8.7 lb-ft)
Note that most non-professional torque wrenches are not very accurate below about 15 ft/lbs, so it is recommended to use an in/lb wrench, in which case the torque settings to use would be from 86 to 104 lb-in.
