By the way, you mention the P0410 code. I've never had this code.

I know this is jumbling everything together, but one thing since the ea/isc is indicated somehow with the limp mode, in other posts I've mentioned that at a stop with the a/c on, when the compressor kicks in, the engines drops rpms and stumbles for a second before recovering. Never has stalled. Looking at JimF's site, I see that the EA/CC/ISC is reponsibile for the following:

"When the A/C compressor is turned on, the throttle valve opening is increased just before the A/C compressor engages. This compensates for the A/C compressor load and keeps the engine idle speed at a nearly constant RPM."

Is my car's throttle valve opening NOT being increased just before the A/C compressor engages? Pointing to an issue with the EA/CC/ISC?

Thanks.
