Hello guys

Here in Chile, we just entering into the summer

I'm actually use the explorer about 2 or 3 times at month, and it work fine.

In winter and spring, all fine, normal idle at start and warm.

But now, with high environmental temperatures (95-100F) and with the AC engaged, in city I got high idle.

I mean, no so high, but about 1000 - 1200 RPM which I'm pretty sure isn't right.

If I turn off the A/C, the RPM remain into 1200..

Any clue?

Regards

PDT: no check engine light, no codes at all

Last time that I checked, fuel trim was between -2% and 3%
