Check out this entry at a Police Interceptor Specialty Site: http://www.p71interceptor.com/ For informtion specific to the Idle Air Control Valve: http://www.p71interceptor.com/repairs/iac/ "Install a new Idle Air Control Valve (IAC). One day, the engine decided it wouldn't idle unless I depressed the accelerator pedal with my foot. While holding my foot on the accelerator, the idle was very smooth but as soon as I let up on the gas pedal the engine tachometer reading shown on the connected scantool would drop so low that the engine would stall. The symptoms were consistent with a defective iac valve, so I gave the iac valve a couple hits with the butt of a large screwdriver in an attempt to bring it back to life. Sure enough the symptoms disappeared and the engine idled as it should. The special ordered iac valve arrived a couple days later, and only required the removal of two bolts to install it."
