Engine Performance problem
2005 Suzuki Forenza 4 cyl Front Wheel Drive Automatic 83000 miles

I have a 2005 Suzuki Forenza. The engine light is on and the car idles high (in park between 2000 - 2500 RPM, in drive about 1000-1500). I can hear what sounds like a vacuum line disconnected, but cannot locate one. I took it to the shop and they are saying that it is the EGR valve. I have put a new EGR valve on the car but the problem persist. Also when driving, if I come to somewhat of an abrupt stop, the car jerk as if the transmission is changing gears. Could the problem be the AIC? Would this cause the engine light to come on as well?

Unplug the IAC module when the warms up and driven for a bit, does that bring the idle down?

Take a can of carb cleaner, and spray every square inch of the engine with it running, if idle changes suddenly you have found a vacuum leak.
