RRC Air Condition Question... - Land Rovers Only

keninmorganhill · 04-02-2008, 11:54 AM

Fellas,

Here's a good one I'm hoping someone might have an inkling about.

I have a 1988 Classic with A/C that blows way cold and runs just fine. Strange thing is though, that occasionally.. when I start the A/C and the engine idle is low, the engine will die.

I can start the engine again, and give it (the engine) a little gas and then she'll run just fine.

I just don't understand why the A/C would kill the engine though. "???"

This engine dying thing too... only happens when I starts the engine with the A/C on. (ie- "Idling low."

Any idears as to why this happening?

Thanks,

Ken (in Morgan Hill, CA)

when your a/c compressor comes on, it puts a very large load on your engine. if your idle is set too low, it may cause the engine to die.

Yep...sounds like idle is too low...there is a good write-up on how to set it on Rovers North web site under tech articles. You might also want to clean the idle air valve (stepper motor) it may help too.

I'll give the idle speed a looksie then. :-)
