Default 1994 surging badly

Hi all new here , I have a 1994 Camry sedan auto 2.2 lt. It starts fine idles fine however once I accelerate to approx 40km this really bad surge happens n constantly. If pedal is pressed harder it the surge gets larger(its already a very big surge). It will not raise speed but the car jerks to accelerate the deccelerates every 2 seconds. No fault code flashing. Any information to start on this would be appreaciated.

Thanks

Update ... Put into test/diagnosis mode no faults detected . Fuel pump checked and pressure still no answer.

IAC valve controls engine idle.

Check fuel pressure regulator.
