Googled for that, got lots of hits. Most to do with power steering overloading when wheel hard over. Stole this reply, eg.
"....There is a power steering pressure switch. When the steering is turned, this switch sends a signal to the engine computer. In response, the engine computer commands the fuel injectors (and, maybe the idle air control valve (iacv) to inject a little more fuel (or, a little more air, from the iacv). If something in this circuit isn’t working properly, the engine won’t get that little boost it needs when the extra load on the engine is applied, and the engine will stumble, or stall.
Inspect a couple of spark plugs. If any don’t look real good, replace them.
A dirty intake tract (the big plastic tube and the throttle body) could be restricting air flow into the engine cylinders. The intake tract, iacv, throttle body bore and throttle plate can be cleaned with Throttle Body Cleaner spray. Disconnect the large plastic tube and spray toward the throttle body. Run the engine until it clears. Repeat as necessary."
