Renault Clio misfire

Car: Renault Clio
Variant: GRANDE
Model Year: 1998
Categories: Engine & Drivetrain
I’ve a 1998 1.2 Clio with D7F 8 valve engine. It’s misfiring and failed MOT on emissions. Pot 2 is the culprit. No probs with compression and no faults reported on ODB. Coil set, plugs (0.85mm gaps) and leads all renewed, no improvement. All 4 injectors replaced. no improvement. Swapped injectors and plugs with pot 1. Still no improvement. Rocker clearances checked and all OK. Can somebody suggest what to do next please?

What are the individual cylinder readings ? If it has a timing belt , has it been replaced and timing checked ? Checked for a partially plugged exhaust and / or cat convertor ?
