Go from least expensive to expensive
As people mentioned above and more....

First I would check and/or clean
1 MAF and throttle valvue cleaned. ~$5-7
2. Plug (if you suspect) $15ish
3. Vacuum hose (forgot the price for Hondas)
4. Transmission fluid. 3 HONDA bottle and do mini flush and put another 3 qt after 3mo. (recommended from older hondas)*
5. other stuff mentioned above or thread


* My sister purchased a 2000 accord w/ 70k for $600 from her boss around 2015. Her boss thought it was a bad transmission. Many times, it is wrong ATF fluid and drives weird. After 2 flushes (3qt at at time with proper OEM Honda fluid), it was perfect running shape.
