It's called IAC - idle air control valve > Did the RPM'S stay at 2000 or drop back down ? The PCM engine computer controls IAC valve according to engine load . Put it in gear , turn on electrical loads , headlamps , A/C etc... an the RPM raise's up so engine will not stall . More then likely the throttle plate needs to be cleaned , they get gummed up an stick at higher idle . Quick Tip Throttle Cleaning EricTheCarGuy If the IAC valve were gummed up the idle would be low or erratic . On some engines a vacuum leak will cause high idle . Videos on youtube checking for vacuum leaks .

    the rpms stayed up, we turned it off twice before it finally come down to about 900, i noticed while he was driving the rpms would go up till he gave it a lil gas and it would come down again. when i turned the a/c off once home the rpms down very low.

    He shows you in the video , yours will be pretty just about the same . The black rubber hose coming from the air filter to the engine ,take that off . On the engine side look inside while someone moves the gas pedal .You'll see the throttle plate move .

    we found a hose off going from the mass air flow pipe, between auto zone and napa they sold us a rubber ring and a valve they said should have been on the end of the hose , on the back side of the motor. i can get my hand to it but not get the rubber ring in. there is a bracket in the way. do you have a diagram we can use to figure out where it goes?

What did you use to clean the MAF? Most cleaners for throttle bodies and carburetors will damage the MAF. You must use cleaner specifically designed for MAFs to ensure that they will not be damaged during cleaning.

When i start the car it revs up to 2000 rpms or sruggles at around 200 or 300 rpms. After it warms up the problem seems to go away. Their is no check engine light on.

You have a vacume leak, and once the temp sensor starts to read after the warm up the ecm starts to control. I would also check IAC idle air control valve.

MASS AIR FLOW SENSOR? 1991 Dodge Stealth RT

Yeah sound like the Mass Airflow sensor (MAF). This is one of those items you really shouldn't get at a junk yard.

Just went for inspection, got P0551. no idle

It's an issue with the pressure sensor in the power-steering lines, it needs replacement, if you're going to do this yourself, make sure you do it quickly and try to catch any fluid that might drain from the line in a clean bowl, that way you can reuse it, after installing the new sensor, refill the power-steering fluid and turn the steering wheel lock to lock 20 times, that should bleed any air from the system.
