Default Fiesta MK3 Zetec Conversion

hello,
hoping someone can help me.
i have just completed installing a 2.0 Silvertop into my previously HCS MK3 Fiesta.
I’ve got the engine running, it pulls well, sounds great and idles spot on from cold however when it’s hot it hunts I’ve checked for air leaks, changed the idle control valve not sure what to do from there?

Try unplugging the maf sensor when it's hunting and see if it improves.

hello,
i did try that and it didnt change the idle. I’m starting to question the lambda sensor, would a faulty sensor Cause hunting on idle?
