'91 22re Idles surge w/A/C on and brake pedal depressed.
« on: Jun 22, 2018, 12:44:54 AM »
Like the title says, the idle surges with the A/C on and brake pedal depressed.

Idle w/a/c off is about 800, turn A/C on and it jumps to about 1500, no issue until you depress the brakes, then the idle drops, rises moderately back to 1500, then drops.

I adjusted the A/C idle up screw, dropped the rpm's to 1200, same response, only slower for the rpm's to climb back to 1200, then drops to back to 8-900,.  I kept adjusting it a little at time, cycling the throttle, depressed the pedal,  until it stopped surging.  However, at the point it stops surging, when you turn the A/C off, and then back on, the rpm's drop, which was the issue I tried resolving last yr.

Now, the kicker is, if I use the throttle to raise rpm's to 1200 or 1500 with the A/C on, while the brake pedal is depressed, there is no surge like there is when the A/C idle up raises the rpm's.

I am I just not finding the sweet spot?

Yah, thought that as well as I have it usually set about 1k, except when being smog checked. I will mess with it again this afternoon/evening.

Might have the problem located, yesterday I messed with it again, and this time I couldn't get the idle to change until I had the idle up screw all the way out, checked the VSV, and it would open, but the ohms are out of spec., will replace and see what it does.
