My car is high reved at 2000 rpm wont go down

I have a 2003 tiburon 5 speed, i currently replaced the throttle position sensor, mass air flow sensor and rebuilt my throttle body. When i turn it on it stays on 2000 rpm??? what can i do next, people tell me it might be the ecu but i dont know..

Have you tried just disconnecting the battery for a half an hour or so? Your ECU probably just needs to forget what it has learned and relearn it.

2003 ford explorer idle surged on me driving. Stopped and put in neutral went up to 3000 rpms. Fast idle now


Given all the electronic sensors that could cause this problem , your best bet is to take it to a qualified repair shop where they have advanced testing equipment . Just so you do spend all your money replacing parts ,,here is just a couple that can cause this problem ! Idle air control valve , throttle position sensor , vacuum leaks , map sensor . dirty throttle plate . mass air flow sensor . A qualified repair shop has a scan tool that can check data for all these sensors .

What is a solution to fixing the mass air flow system, with code po121


DTC P0121: Throttle Position (TP) Sensor 1 Performance
Circuit/System Description
The engine control module (ECM) uses the following information to calculate an expected airflow rate:
?€¢
The throttle position (TP)


?€¢
The barometric pressure (BARO)


?€¢
The manifold absolute pressure (MAP)


?€¢
The intake air temperature (IAT)


?€¢
The engine RPM


P0121 The predicted air flow and the predicted MAP combined are outside a calibrated range for more than 3 seconds.
Circuit/System Testing

  1. Inspect for the following conditions:
  2. ?€¢
    Vacuum hoses for splits, kinks, and proper connections as shown on Vehicle Emission Control Information label


    ?€¢
    Inspect thoroughly for any type of leak or restriction


    ?€¢
    Air leaks at throttle body mounting area and intake manifold sealing surfaces


    ?€¢
    Throttle body for dirt, debris, and coking--Refer to Throttle Body Cleaning.

  3. Allow the engine to reach operating temperature. Observe the MAP Sensor Voltage parameter with a scan tool. Voltage should be more than 0.8 volt and less than 4 volts.
  4. ?‡'
    If more than 4 volts or less than 0.8 volt, refer to DTC P0106.

  5. Idle the engine. Observe the MAP Sensor kPa parameter with a scan tool. Increase the engine speed slowly and then back to idle. The MAP sensor kPa should change smoothly and gradually as engine speed is increased and returned to idle.
  6. ?‡'
    If the MAP sensor kPa does not change, refer to DTC P0106.

  7. Take a snapshot of the engine data list while performing the actions listed below. The mass air flow (MAF) sensor g/s should change smoothly and gradually as the engine speed is increased and is returned to idle.
  8. ?€¢
    Idle the engine.


    ?€¢
    Increase the engine speed slowly to 3,000 RPM, then back to idle.


    ?€¢
    Exit from the snapshot and review the data.


    ?€¢
    Observe the Mass Air Flow (MAF) Sensor parameter frame by frame with a scan tool. The MAF sensor g/s should change smoothly and gradually as the engine speed is increased and is returned to idle.


    ?‡'
    If the MAF sensor g/s does not change smoothly and gradually as the engine speed is increased and is returned to idle, refer to DTC P0101 or P1101.

  9. Inspect the throttle body for the following conditions:
?€¢
Loose or damaged throttle blade


?€¢
Broken throttle shaft


?€¢
Any throttle body damage


?‡'
If any of these conditions exist, replace the throttle body assembly.

It starts but as soon as it's put into gear acts like it wants to go but quits.


Could be a few things. But here are the obvious. Check for a vacuum leak around the intake. When you put the car into drive it starts putting strain on the engine, a vacuum leak will give it too much oxygen and cause a fuel mixture issue / reading.
If nothing wrong there, you may have a bad throttle position sensor. When you put the car into drive and it starts putting strain on the engine it will pull the idle down then the sensor will adjust it automatically. Hope this helps.

What do I need to do with the code p2106


P2106 - Throttle Actuator Control System - Forced Limited Power

Engine power and RPM's will be limited and cruise control will be disabled due to a throttle fault. This occurs when one or more throttle positions sensor readings are out of range or do not agree with each other. Sometimes this code is also set if the throttle plate cannot return to the idle position due to carbon buildup in the throttle body (you might try cleaning it). The code can also be caused by a bad mass air flow, output shaft speed, turbine speed sensor, or crank position sensor. If the throttle body is clean, operates smoothly, and no other sensors are failed, then you might have to just replace the throttle body.

You might have bad connection in wire harness, Wiggle the wires while reving the engine. Do this at night to see any sparks in the dark. Look for sparks around the Spark coil. You may need new coil.

Engine runs rough and stalls sets a p0068 code on a 05 dodge durango


P0068-MAMFQLD PRESSURE/THROTTLE POSITION CORRELATION
' Image
Theory of Operation
This DTC sets when an unexpected high intake manifold air flow condition exists that
can lead to increased engine speed and puts the NGC into a High Air flow Protection
limiting mode. The High Air flow Protection feature includes RPM limits for when a
Throttle and or MAP sensor limp-in fault is present.
When Monitored
During all drive modes.
Set Condition
If vacuum drops below 1.5Hg with engine RPM greater than 2000 RPM and closed
throttle. One Trip Fault. Three good trips to turn off the MIL.
Possible Causes
-VACUUM LEAK
-RESISTANCE IN THE (FS56) 5-VOLT SUPPLY CIRCUIT
-(FS56) 5-VOLT SUPPLY CIRCUIT SHORTED TO GROUND
-RESISTANCE IN THE (Kl) MAP SIGNAL CIRCUIT
-(Kl) MAP SIGNAL CIRCUIT SHORTED TO GROUND
-RESISTANCE IN THE (FS55) 5-VOLT SUPPLY CIRCUIT
-(FS55) 5-VOLT SUPPLY CIRCUIT SHORTED TO GROUND
-RESISTANCE IN THE (K22) TP SENSOR NO. 1 SIGNAL CIRCUIT
-(K22) TP SENSOR NO. 1 SIGNAL CIRCUIT SHORTED TO GROUND
-RESISTANCE IN THE (K900) SENSOR GROUND CIRCUIT
-MAP SENSOR
-THROTTLE POSITION SENSOR
-PCM
Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding.

Will not run over 25 mph


check your speed sensor and your crank position sensor. I did a clutch job on my RIO and forgot to plug the crank sensor in all the way and it wouldn't go above 25 Mph. If that doesn't work, try replacing your Mass air flow sensor, it sets on top of your throttle body and bolt to your air box.

Car won't idle


First if the "service engine" light is on I would have a local retailer or garage see what the codes are. For possible TPS, IAC, or mass air flow problems. TPS being "throttle position sensor" IAC being "idle air control" If a light is not currently present, listen under the hood for a hissing noise or signs of a vaccum leak.

My 2003 hyundai tiburon 2L iddles at a steady 4000 rpm and wont iddle down. How do I fix this??


There r 2 cables on a gt 6 speed that r located at the top of the engine in back.. Do not touch the rear cable unless ur tibrron is shifted hard. The front cable is ur drift idle, theyre 2 nuts tightend den to secure it at a certian level , untighten the nuts and simply ajust the 2 nuts backwards do the cable isnt so tight and allows the engine to drop idle wen accelerater isnt pressed. Then do the same to the rear cable(2nd) cable untill u have ur tibron sounding just right..only sol_tion
