I am getting a code for cylinder 5 misfire. I would like to change the plug boot and ignition coil. The problem is I don't know which cylinder is number 5.

OK the Number 5 cylinder is at the front of the compartment drivers side, they number 1-4 front to back on pass side then 5-8 on the drivers side front to back. this is usually a bad plug what it looks at is the computer and then the O2 sensor sees how much unburned is passed. you might have a bad, plug, wire or the dist is dirty.How do I know which cylinder is number 5.?
3rd one back on the pass. side.How do I know which cylinder is number 5.?
Cylinder closest to the radiator on the driver's side. Those engines are known for the coils going bad. Instead of a plug, wire, and distributor they have a coil that sits on top of each spark plug so you have to replace the whole thing. About $62 at Autozone. Change the plug too because it probably fouled out. Just be careful to get it in straight when the engine is cold so you don't damage the threads.
