Default 87 FC N/A Idle issue

So i've recently got my 1987 Na Fc on the road and it ran spot on for a the first week apart from having a surging issue at 1500 rpm which goes away about 2000rpm and now it will idle a bit lean on a hot start, mind it still starts perfectly fine and hardly has to turn over.

If I turn the car off and on again the idle will return to normal, tps has been adjusted can't see any obvious vaccum leaks the idle is normally steady when warm and I have also tried another ecu.

To note for any US users this is slightly different as it has a n322 ecu and distributor.

Any advise, thanks!
