I have a 2003 Ford Crown Victoria & it's idled up high. A MECHANIC said that I need to replace the idle sensor. Wat should I do to save money

You can remove the iac sensor and clean the pintle and seat and reinstall, also clean the throttlebody plate. Check for vacuum leaks at the manifold. Try moving moving the idle air control sensor pintle out to (iac) contact the seat to close the idle gap. Reinstall and dont plug it in to the harness. See if it idles correctly, if your high idle is gone then, there is probably a dead spot in that sensor. If the idle stays high you will need a vacuum gauge to connect to the engine a get a reading to check engine idle vacuum, whic should be 15 to 21. Anything lower indicates a leak from intake areas such as injector o-rings bad vacuum tubes or hoses. Always prove things before replacing parts. Good luck

Idle is going up and down

sounds like a vacuum leak which tells ur computer ur gas is too lean (because of the vacuum leak) and makes up for it by giving it more gas when actually it doesn't need it...chek all hoses, carb bolts, gaskets, intake manifold bolts, etc etc...anyplace where air can get to the carb besides the opening of the carb which is the ONLY place the air should enter...

Will not stay running when you give it gas

This sounds like a fuel problem. Possible clogged fuel filter. Possible fuel pump not working to specifications. Check for proper fuel pressure at idle and also when you give it gas. Fuel pressure should be anywhere between 13-20 at a minimum. Also possible vacuum leak or a missing or disconnectd vacuum hose.

Jeep won't stay running when idling

The throttle plate is supposed to be closed at idle...Idle air enters through a port controlled by the iac valve which takes its instructions from the computer. BUT...the computer only knows what it has been "told" by other sensors...throttle position sensor map sensor and manifold air temperature sensors all have a lot to do with this. The iac valve can be removed and cleaned with carb cleaner, as can the passages that lead to and from it. DO NOT turn the plunger on the valve and don't loose the small "o" ring seal.
Always check all vacuum hoses and connections before working on other parts. Often you will find a small vacuum leak that when corrected avoids major work. You can test nearly all components using a digital volt ohmeter and a manual such as chiltons or haynes as a guide. (cheap...around twenty bucks) Careful testing avoids buying expensive parts you don't need.
Ask if you need specific help with anything.
Good luck

I just put in a new carburetor in my 87 corolla sr5 and it has cold start problems and the idle wont stay at a set rpm all the time

You probably have vacuum leaks somewhere. Be sure your base gasket is tight, and all your hoses are tight and not cracked. Use a length of fuel hose held to your ear with the engine running, and listen for a hissing.
