aye, prob a failsafe incase the IACV sticks.
on my 98 1.3 slx loom the IACV alone works fine without the waxstat (fast cold idle then normal warm idle)
but my other 93 1.3 slx loom the IACV isn't workin properly (slow cold idle then fast warm idle symptom). swapping over the 2 TB's gives the same outsome for that loom so i think either the older ecu isn't controlling the IACV properly or the IACV loom is faulty.
