Struggling power
 

Have you run any form of diagnostic?
Is it modified?
What fuel are you running it on?
The list goes on. More details are needed.

Aye, if it's an import, when was it imported and has it been mapped for UK fuel?

i assume a 95 year car still has a cel light ? and there is a way of checking any faults on it but i can’t remember exactly how but i’m sure can be found on line, it’s connecting wires under the dash from memory , i’m assuning due to age no obd port ? but as above code reading first , it sounds electrical to me , leads and spark plugs would be my first choice
