I have a 1997 4.6L Triton engined truck, during lockdown it stood for 2 years and the batter died, I have fitted a new battery and it starts and ticks over fine but when driving feels uneven, does not pull well but will still carry a load and go at full motorway speed (or over) put in neutral and floor the throttle and it hits mid rev range and misfires. Being in Europe I have no local knowledge base to use so basically HELP!! its been like this for over a year now although I only use it when I need to

 

Could be any of the following:

Clogged fuel filter
Dirty fuel injectors
Spark plugs
Plug wires
Coil packs
Low fuel pressure
Bad fuel
Dirty air filter

 

lets apply common sense and start by checking codes

 

Sorry if I lack common sense but where do these codes appear on my analogue dashboard display please?

 

LoL, no

you have to have it scanned, any autoparts store can do it…

 

You need a OBD2 scanner. I don't know if parts stores do this in Europe but any decent repair shop should have a scanner. You can also buy a scanner (code reader) on Amazon. Search your local Amazon page for OBD2 scanner, they start around 20 euros.
