help please

i recently fixed the rattle from my left muffler. I drove the car today to air my tires and got a CEL coming home.

my durametric says code p303, which i understand is a misfire. i noticed a small leak in cylinder 3 when i looked under the car. this is the first cel i got since acquiring the car last year, advice on how to proceed pls. TIA

The misfire is only on cylinder 3? That is the only code?

If so, then you likely have a cracked coil or bad spark plug.

You need to have a look.

I have also had this issue from the spark plug socket - (the part between the coil and the spark plug) - (996-602-103-01 if your car is -01, or 996-602-105-00 if your car is 02-) This part usually comes with the coil, but you can get it separate.
