The reason is that the car revs do drop under the power steering pump literally resisiting the crankshaft via the main front belt.Same as the air conditioning.Otherwise the car would literally turn off when these accesories are turned on  Matt..you buddy stav is just a pm away champ How ya been ? Hows the family? |
Thanks Stav. So this would explain why the idle lowers when I use the power windows also - the alternator is loading up.
Why do the revs drop so low though when my BA doesn't do that.
Also I disconnected the battery today because I was working on the
BEM. Wouldn't this reset the base idle? What should I do when I reconnect the battery? Do the 2 minute a/c on, a/c off e.t.c. to set the idle? Or just leave it and drive normally.
Cheers.
