A few possible reasons

Catalytic converter stuffed
Tyres are too big without gearing
Carby probs, maybe blocked jets
Low compression/head gasket
Ignition timing
Valve clearances
Old fuel
Fuel filters
Fuel pump fouled spark plugs

Realistically it can be anything.

Have you any or much mechanical knowledge? What have you already tried?

Start by getting a service manual or Gregory's workshop manual, start at the top of the list in 'troubleshooting' and work from there.

More importantly, low on power compared to what? What were you driving previously? What size tyres are fitted?

The OP's profile says SJ410V 1985. Is it a 1L engine?
