I would replace the sensor, make sure the connection to sensor is good, theres a way to test the connection wires but get confusing if not a tech,replace the sensor.

I hav a 98 Malibu Was idleing funny change the tps didnt fix it now when driveing it acts like it wants to die but when i stop it dies still acts like the idleing is still offf


There are a few things you can check for, 1. the idle air control valve for carbon and the same for the throttle plate having varnish or carbon build-up . Use spray carb. cleaner if any of these are black with carbon.2. A dirty mass air flow sensor will cause stalling and Idle problems . You can get cleaner just for mass air flow sensors ,don't use carb.clean ,or brake clean ! Or you could possibly have a vacuum leak ! check all vacuum hose , you can spray carb cleaner at intake gaskets to check for leaks , but be careful it is flammable !!!

Almost no acceleration engine will not top 2K RPM under load.


Have you checked the air inlet sensor on the air filter. If this fails the engine goes into safety mode which it seems has happened. I don't know the specifics of the Santa fe but this is a feature of most modern electronic engine systems.

Code p0113 (IAT) aand code p0103 .. were i can finde the solution??


The codes refer to a faulty maf or mass air flow sensor (its is the sensor which is between the air cleaner housing and the throttle body. The IAT is a variable resistor which goes up or down with the temp of the incoming air. The Iat sends this info to the ecm in voltage which adjusts fuel injector pulse width. Now that you're better informed first try to clean the maf sensor (unplug connector then unbolt and remove sensor) with either a can of compressed air like keyboard/mouse duster or mass airflow sensor cleaner ($10) at most auto parts stores. Spray the plug connection as well as underneath and up into the sensor itself. The maf spray dries in about 20 seconds, reinstall sensor, start vehicle see if there is a noticeable difference, have codes erased, stop vehicle, restart and see if codes pop back up. If so the sensor is not dirty, but faulty and you'll need to replace it. If you need any further help or clarification just ask

99 Grand Prix idles funny, dies got code p0102,


this vehicle most likely has a mass air flow sensor it may have got accidently unplugged or the air tube from mass airflow to engine is not connected well or it could be that you have indeed a bad mass air flow sensor they do make a special cleaner that you may want to try before purchasing a mass air flow sensor or purchasing one from salvage yard the symptoms you describe would be created by a bad massair flowsensor

Check engine light


No the light is fine its the computer or there is a intake leak somewhere causing the mass air flow sensor to not work correctly, also a cracked hose may be giving a false reading. Get a mechanic to test it with a voltmeter and ohmmeter using a vacuum gauge to make sure it is the mass air flow sensor

When car is idling it misses a beat


sounds like it could be iac motor (idle air control) or maybe Mass air sensor . No check engine?? Also check and clean EGR ... at least thats a place to start.... You can also remove and clean IAC motor with carb cleaner.
