If the engine has a P0305 DTC (Data Trouble Code) for a "cylinder 5 mis-fire detected", then the first thing to do is to do a compression test to determine if the mis-fire is actually being caused by a mechanical problem, or an electronic problem.
If the engine really does have low compression on the #5 cylinder then that is caused by a mechanical mis-fire and nothing electronic will repair it, and the most common causes for a mechanical mis-fire would be a burnt or bent intake or exhaust valve, a warped cylinder head or damaged head gasket, or a damaged piston. You can call around and find a repair shop that will do a "compression leak down test" if you want to know exactly what is causing the compression leak without any dis-assembly to the engine.

It is most likely a valve not closing,check the valve springs on that cylinder.
ENGINE MISFIRE
There are few possibilities that can cause engine misfire
issues. It can be issue with spark plugs or faulty spark plugs. Also get the
compression test done for cylinders. If any of cylinder shows low compression
then required, then that particular cylinder will cause misfire.
Also get obd codes scanned, the error code will let you know
which cylinder is misfiring or all cylinders are misfiring.
