Civic knocking while pushing harder and acceleration lag

Question

I have civic 98 with D16Y4 engine with automatic transmission. It knocks while pushing gas harder during high revs. I'm currently using ron 92 and I tried ron 97 but faced knocking on all I even tried shell V-Power but result remains same. I guess it's engine timing issue? Also whenever I instantly push gas engine take 2-3seconds lag then it respond. Any expert opinion are welcome

Answer 1

All issues were due to bad ignition timing after setting up timing belt according to service manual engine's power restored and also acceleration lag is gone. Thanks everyone for taking part in solving issues :)
