Are you going to do your own work or have a shop do this?

Remove the valve cover. Then determine if the valve is stuck and the possible reason.

It could be carbon on the valve seat, a burned valve or a stuck valve.

Suggest this:

Remove the passengers side tire and a splash shield to allow access to the bolt that holds on the harmonic balancer (pulley).

Remove the spark plugs.

Have someone rotate the engine CW while you watch the No 2 valves.

You want to determine that after each valve is pushed, it comes back fully.

There are two exhaust and two intake valves that operate at the same time. You can compare the two exhaust or intake valve movements and valve clearances at TDC.

TDC is when the crank pulley mark is at the 0 degree mark on the timing cover.

The valve clearance engine cold should be intake valve .007.-011 inch, exhaust valve 0.011-0.015 inch.

Also watch the valve moment. One valve may stick or be slow when returning back to the closed position compared to the other.
