Took the inlet of at the weekend to inspect the valves and injector (cyl 4)
also gave the throttle body a good clean being a tad cruddy
the offending injector
The inlet valves were surprisingly covered in carbon/vapor deposits (inlet walnut blast done 9 months ago) too be honest i wasn't expecting them/ looking this bad already
inlet plates just as bad
everything was cleaned also fitted new:
*pcv gasket
*bottom pcv pipe
*inlet gasket
*injector
*cam follower checked
*vac pump o ring replaced
She now runs great no misfires :)
Next job will be to clean the filthy thing
