tps is most likley then, if the ecu spots a open throttle it opens the iscv.

check wiring,and base setting

Had a escort gti, and we changed the iscv and it made no difference, the TPS did the trick and it never did it again in the 2 years i owned it

Or a crappy chip, my EA chip did that anywhere between 1200-1500rpm when warm, now with GGR chip back in due to problems wiht EA one it is rock steady at 900rpm.
Mind you the AFR was 10.5 on the EA chip!!

A common problem or so it seems!

When mine did this it was a dead ISCV, replaced it twice, once with a supposed brand new ISCV and I still had idle problems, replaced it with a second hand item and it's pretty sweet and well behaved now!

Where did you get your brand new ISCV from as they are no longer made I don't know of anyone who stocks them anymore!?
