Do you have a way to monitor the ECU while driving? Any cheap ELM327 unit would work. I suspect you have a fueling problem and are leaning out -- fuel filter, fuel pump, injectors.

I forgot you are dealing with a pre-OBD2 system, so scratch that.

I'd have put a pressure gauge on the fuel rail before changing fuel pump and injectors though. A weak pressure regulator for example could let the car run fine at idle and low loads, but it'd fall on its face at WOT.

ok I’ll try and put a fuel pressure gauge on it and let you know how it goes.
