Most likely spark plugs and wires. Coils usually kill two cylinders at the same time. Use only ac delco parts. trust me, it is something you don't want again soon.

If the check engine light is not on, I would look at the fuel pressure and vac leaks. Mechanical problems can occur without triggering the check engine light.

Error code p0300 indicates rough idle and p0305 indicates engine misfire in cylinder 5. Check for faulty spark plug and its wiring. Also check for ignition coil and distributor. Replacing spark plug and its wiring may resolve the issue.

Engine skiping at idle.


If it is actually skipping, the check engine light should be on for a misfire and tell you what cylinder is missing. If it is a little bit of a rough idle, could be plugs, fuel, bad motor mount, or a bunch of other things.
