95 ford taurus Sho MTX model 3.0 liter 100k miles..
My SHO will be running perfectly fine then when i downshift to stop and leave it in first with my clutch down (just a example does it whenever its halted) it will just not stay at a certain RPM.. it will stay about 1 and half where it should be then it just goes below one and lasts for a very long time until i go again and ill have this problem over and over again.. its just getting to the point where i dont wanna drive it.. im 16 with no $$ so cant buy a new car... its frustrating to take off in because if its at a low RPM ill have to give it more gas then i usally have to... me and my dad think its the idling censor he bought a censor i forgot wich one it was and it didnt do anything.. cleaned a filter chip (your not supposed to do this buy a mechanic suggested it to us- car idled for a good 2 weeks then my dreams were shot when it stalled due to bad idling :[)
And also sometimes ill have this Clicking sound in my heater its really annoying it goes away for a month and comes back.. its really frustrating to drive to because its really loud.. i know this topic should be under strange sounds but i didnt wanna make 2 posts.. thank you

Jordan;
The idle speed actually sounds too high. When you said 1 to 1 1/2, to me that sounds like 1000-1500 rpm. Hot idle, in neutral, should be around 700-800 rpm. At the higher idle speed, I'm sure that it's easier for you to take off from a stop, but that is not the correct idle speed. Cleaning the idle air control motor will, most of the time, correct this problem on Fords. Also, cleaning the throttle body and the MAF sensor. It's also possible that someone has 'messed' with the idle stop screw. It's a common mistake people make, thinking it will raise the idle speed, but just throws the throttle position sensor off. Another thing to check, watch the engine temperature. Is it getting up to, and staying in the normal area of the guage? If it runs too cold, it will want to idle too fast. If dad can't do this, you really should save up a few bucks and have a tech check/adjust this for you.
The heater noise; The heater blower motor, on the passenger side, behind the glove compartment, is nothing more than an electric motor that spins a fan. The fan is shaped (and looks like) a wheel in a hamster's cage. The bearings in the motor could be going bad, or some debris has gotten into the heater box which is contacting the fan as it spins. A pen or a pencil dropped through the defroster vents can work it's way into that box. Also, mice like to build nests where it's warm.

Jordan; Exhaust sensor? Oxygen sensor? Working on the radiator? Hmmmmm. Just a wild guess, but if you were having problems with the radiator, could have been low on coolant, which would affect the coolant temp sensor reading to the computer, causing the idling problems. For the future, you don't want to run the engine with the sensors disconnected or removed. Yes, it might run better for a short time, but depending on what is disconnected or removed, you could cause serious engine damage. These sensors control fuel supply. Too much fuel can damage the engine quickly. But....glad you've got your baby running again. Good luck.
