    You will see a boot, Little black rubber piece on the top of the EGR valve. Make sure none of those are cracked and noe of the vacum lines are cracked. With the ingition turned to the on switch, take a volt meter and check the power at the IAC, the IAC is lcated right behind the EGR valve which is located right behind the air intake on the top of the motor. IF the IAC is not getting any power then replace, if it is getting power then replac the EGR

I have a 95 Chrysler Concorde upon start it hakes and is very rough on idle. when i accelerate it chugs like it doesn't want to accelerate.the check engine light is not on.

Sounds as if there is one or more cylinders misfiring. Possible defective ignition coil/spark plug/s/ or ignition wires. IS the vehicle blowing black smoke out the tail pipe? If so, another possibility could be an over fuel situation caused by a defective sensor or leaking fuel pressure regulator. My guess would be a mis fire causing the engine to not fire on all cylinders

High idle o n a 1996 chrysler concorde. have change the tps and the idle air control valve. i think its a vacum line but i dont know which one. which one s effect the idle

High idle is usually caused by a vacume leak. First place to check is the cold air intake manifold. All hoses, throttle body, and sensors. Throttle Position(TPS), Mass Airflow(MAS), Idle Air Control Motor (valve) IAC. Controls Idle speed

A malfunctioning throttle system can cause both a high idle as well as an engine stall.

A dirty air intake or cracked air intake tube is often the culprit.

If the check engine light is on, take the vehicle to an autoparts store and have them use a scan tool to retrieve any fault code(s) stored in the computer. Most parts stores offer this service at no charge. The fault code(s) will help narrow down the problem/potential problem. Sure hope this helps and best wishes.
