'99, S70 stalling S70

When I attempt a tight turn, especially when the air conditioning compressor is engaged, my car stalls. This also happens in neutral, with the steering wheel in a hardturn (After I rev the engine and the engine approaches idle, it stalls. No engine warning lights).
Anyone had issues like this?
What was the fix?

You probably need a throttle body cleaning. The gunk buildup doesn't allow the electronic throttle, servo controlled actually, to operate properly. I just had mine cleaned in the '99 V70 after the failed AMM was replaced.

How many miles?

Have you ever had it cleaned?

'99, S70 stalling... cleaned throttle body ...now runs like new S70

I took a closer look at the throttle body last night. I didn't realize the build up would be behind the 'flapper'. I applied some carb cleaner to a rag, cleaned it out ... car runs like new.
Thanks Token Ring Man!

The throttle body wasn't gunked up at all. It had just a little 'glaze' in it.

Forgive me, but what is an AMM?

I've got 55k and the throttle body has never been cleaned.

Something I noticed last night... the air conditioner and a hard turn REALLY put a lot of strain on the engine as the RPMs approach idle. What controls the idle? Whatever is supposed to maintain idle at the moment of gear down is apparently failing.

Nope, no odd noises and the power steering fluid is leveled off.

Are you getting any unusual noises at the time? Have you checked the power steering fluid? Post and let us know what it turns out to be.
