2007 Toyota Camry misfire fix
I had a few misfires on this toyota camry i bought to resell. Heres how i fixed it.
Codes I had : P0302 P0303 P0300
Ended up having to replace valve cover gasket , pcv valve , pcv hose , ignition coils, and spark plugs.
I am not a mechanic, just a passionate DIY'er
I am just sharing my experience in hopes that it can help someone in the same boat with misfires
