My car idles too fast like 3000 rpms and the checkengine light is

Check for crossed vacuum lines or leaks.That would definately give you a high RPM.Did you have the computer scanned at all.Dont just change the sensors if their good.Pay someone to fix 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 .

Idles rough aand checkengine light on, changed o2 sensor that was throwing the code and didnt fix


Well first, has the vehicle had a tune-up as of late? Second, if it has had a tune-up, then the possible culprit to rough idling is the Idle Air Control valve or IAC for short. Also, if your check engine light is still on, your still getting codes. What are the latest code(s)?

Had the battery replaced and now the engine idles at 300 rpms.


try disconnecting the battery for about 15 minutes, sometimes this will clear false codes. Reconnect battery and let it idle for a few min. Some cars have to recognize how a car is driven and idled for a certain amount of time. This info is then stored into the (brain) of the car. It may just have your signal from the throttle position sensor messed up and hopefully this will work.

Try unplugging the mass air flow sensor and see if it levels out.If so I would change the mass air flow sensor.If not try the same technique with the throttle position sensor.
