Engine Performance problem
2002 Mercury Sable 6 cyl Automatic 137640 miles

When i start my car in the morning it takes an extremely long time to isle down. Maybe about 4 minutes. And if i drive off before it is isled down it will jerk when driving. This jerking problem will happen also while i am driving regularly and if i let off the gas and press again it will stop jerking. Not only does my car only jerk in the morning but if i ever pull off before it is isled all the way down it will jerk until i let off the gas and hit it again

And no check engine light ON ??!!
scan for codes
suspect vacuum leak
check around the PCV valve and hoses
make sure u pinch them if soft and they don’t return to shape replace them
check idle air control valve
