Hello all,

Does the Idle Control unit just unbolt and unplug? It is a DIY item, isn't it?

I hate to throw parts money at a problem but it might beat throwing diagnostic money at it.

Where is the throttle closed sensor?
How does the idle air pump work and where is it? Do they get clogged or fail?

Does the Fuel Pump Relay act up as the Fuel Pump is ready to fail? What is the procedure to test Amp draw on the Fuel Pump?

Any help? This is to solve an idle problem during warm up.
