Hi all-

My engine runs fine but when I drive really slow like I'm parking or approaching to red light, meaning my foot is not on the gas pedal, rpm get down to like 100 or 200 sometimes and almost stalled. Never stalled yet, but I'm not surprised if it does.

Some says it's vacuum hose. I checked it, it looks new, no crack found.

When I use A/C it's OK, this symptom doesn't happen since engine runs slightly higher rpm.

Maybe there's a simple way to adjust idling rpm? Any sensers to fix??

Thanks.
