Question about 2001 Hyundai Accent
I have two different problems with my car. I've brought my car to the gargage for both problems.
1) My car at least once a week will not start. The started has been replaced, the ignition wiring has been changed. It's a standard. It started last summer(June 2008). It acted up all summer and then winter came (As I Live in Canada) and the problem just stopped. Then the end of March comes (warmer weather and rain) and again at least once a week sometimes every two weeks, it will pick a day that it won't start. Most of the time, it's in the morning or when left a few hours but it will start after a few hours.
2) My car will reve high while in First and neutral. Sometime will will reve up to 3 RPM's while sitting at a light.
My car now has both problems. Last summer I fixed the Throttle position Sensor and we've checked to see if it's faulty and it's not.
Any body have any ideas??
I have an idea... why don't you have a 'qualified Hyundai Technician' diagnose the problem?.. First of all, you describe an Engine Management System problem. I assume it a 1.6 DOHC engine. There are numerous suspect causes for your problem. Example, Idle speed actuator, Cam Position Sensor, Throttle Position Sensor, Injectors, Crank Position Sensor, Manifold Absolute Pressure Sensor, Engine Coolant Temp Sensor, Heated Oxygen Sensors, Mass Airflow Sensor (this one's my favorite.. along with Throttle position sensor), Intake Air Temperature Sensor, and the list goes ON... vacuum leaks, throttle body problems, PCV problems, Oh!.. and let's not forget plugs, wires, coils, fuel pump problems, etc. The one most often found as cause for excessive rev is the ECU (Engine Control Unit). Try this out... disconnect the battery. Take the the pos (+) cable and connect/touch it to the neg (-) cable for 60 seconds.. then reconnect the cables to the battery. Tell me what happens after you drive it for awhile. If it's still acting up... take it in for diagnosis.

I have a 2001 Elentra and the revving up too high issue was a huge one for me. I changed the throttle position tensioner and that was not it. Come to find out it was my cruise control that was going out and it was getting stuck. Disassemble the cruise control and let me know how it runs. I am a girl, but I know more about cars than my hubby does. lol. Just let me know something.
