Default '94 XJ running wierd

I brought my XJ a couple of months and its running a bit ****
every now and again when your cruzing or if you accelerate heavily out of a corner it basically cuts the engine out
Sometimes I can hear what sounds like backfire

Ive changed all the ingnition system bar the coil
Ive put a new air filter in
Throttle body spacer
and Ive had the catilatic converter removed which seemed to help a bit (legal in NZ)

Its been doing it before Ive done all this stuff
My old man seems to think its a sensor cause his wrangler has done a similar thing

any help will be much appresiated

Cheers
