I'm treating this as a last resort. My 88 760 turbo starts and idles fine. However if you blip the throttle or take of down the road and load the engine it has no power and bucks. I've got access to many Volvo parts and I've tried: mass air meter, distributor, coil, fuel pressure regulator, both fuel and igniton ECU's, ignition power stage, dist. cap and rotor, and plug wires. Plugs are OK. I decided since I have a parts car to just do some parts swapping and honestly figured one of these parts would nail the problem. So now I'm leaning toward wiring somewhere. If anyone has any ideas at all, I will entertain anything at this point. Thanks
