OK, so no fault codes coming up, idles OK, accelerates rough, smells like fuel and uses a lot of fuel.
All your sensors are plugged in, vacuum lines are all OK, spark plugs are gapped correctly.
If it vibrating under load it suggests one or more cylinders are misfiring. Without the fuel smell I’d be looking at the coil packs, DFI Module given you’ve done the plugs and leads already. With the fuel smell there’s two ways to approach it. Fuel smell is related to the missing or fuel smell is independent. You said it was using a lot of fuel so if that were mine I’d be covering both bases.
Last night I stepped out a check involving releasing each injector harness in turn. Give that a go and blip the throttle by hand to see if any one injector is behaving differently to the others. You squeeze the clipwire on the connector and pull the connector up in alignment with the injector. When you clip them back in make sure the connector is perfectly aligned to the injector axis.
