Idle speed issue

My smt car had started idling slow.

Took of the rubber inlet hose between MAF and throttle body. 

Cleaned the inside of the tb and valve with WD40 on a rag.

Reassembled.

Now it starts at 2K and then quicly settles at almost 1500.

Disconnected the battery for half an hour, no change.

With the inlet hose off I can see/feel that the throttle valve is not entirely closed: I can push it some 2 mm closed against sping pressure. The throttle cabe is slack enough (and not directly connected anyway).

Is there a TPS relearn/reset procedure?

Or something else I may have messed up? 

Thanks.
