Hi,

For the emission light, pls check/clean/replace the O2 sensors. These sensors could possibly be also responsible why the idle is relatively high. The O2 sensors could be feeding the ECU erroneous signals. The engine management computer then adjusts the air/fuel mixture being fed to the engine also erroneously.

Just a start, do postback how things turned up or should you need additional information. Good luck and Thank you for using FixYa.

When this light is on it means the engine controller has seen a failure in a component or system on the vehicle and needs to be repaired. This is something that should be taken care of, hopefully something cheap. If we can get the codes out of it I can tell you how to test or repair it yourself or know what to expect when you have a shop repair it. To get the codes read, just go to a local auto parts store such as NAPA, Checker, AutoZone, ect. and they should be able to hook a device to the jeep and read the codes coming from it and then from the codes we should be able to figure out what you can do to fix the problem. Reading the codes should be free, so check before having it done and let me know what codes show up.

Check out that  fuel had been leaking around the valve so just  take a valve core stem out of an old tire and replace it .it will start the car up and it will  be fine . Try it.

    also it Could be the throttle position sensor or the idle air controller.check out.

  • fixyy Nov 18, 2008

    to reset the light
    Pull the Neg(-) batter cable. Let it sit for a few minutes. Then put the cable back on and tighten it down. 
    If that doesnt work you have to take it to a shop and have them do it. 

  • fixyy Nov 18, 2008

    If you are talking about the red light on the dash then you don't "Reset" it you need to have the brake's serviced or fill-up the fluid in the reservoir. the light is designed to come on if the fluid is low. 



  • fixyy Nov 18, 2008

    to reset engine light
    remove the ecm fuse for 30 seconds will clear the codes

You probably mean 1000 RPM. Sounds like Injector and fuel pressure problem. Could be the control box.

Idel problem on 5.7 1995 silverado


You engine is TBI, It uses a MAP sensor check the vacuum line for crack and make sure yo have a good seal, The distributor also check and make sure the pick up does not have corrosion which causes the relutor to stick. As for the EGR it would cause a misfire, and yes the do fail. I am sticking with the IAC as a problem its a stepper motor and has a high failure rate, chack also the ECT (engine coolant temp sensor) for corrosion that gives false reading.

Idels fine when driving it sometimes loses power and stalls if you rev the idel above 3000rpm it stops and runs fine till you stop or slow down the idel below 3000 rpm it shutters and...


If you don't have a check engine light, Start with the air and fuel filter, work your way up to a tune up. Clean the throttle body as best you can on the inside, behind the throttle plate/s

When started idels high about 2000 rpm then drops when hot cold ?


the iac probably has carbon built up around it this controls the idle speed try cleaning it first,if not it could be a bad iac or a vaccum leak that the iac takes some time to compensate for to control idle.

High idel


You may have a bad control valve or regulator. Did you adjust the idle properly?

1. Disconnect the connector on top
2. Adjust idle to around 650-700k rpm
3. Reconnect the electrical connection

After reconnecting, the idle should jump up around 700-750k rpm.
The idle screw is fail safe setting in case the ecu cannot set the idle. The rpm's set by the idle screw are supposed to be below the ecu/stock idle.

If this doesn't work, you may have a dirty or bad Idle Air Adjuster and/or Air Regulator. For information on cleaning that, you can refer to this page http://s95014253.onlinehome.us/63104/157335.html

You can test the IAA by supplying power to the plug with the car off. Listen for any clicks or humming. That will signify that it still may be working but is possibly stuck. The Air Regulator is for high idle for warming up your car. It has a bi-metal spring inside that rotates a disc closing off an airway to bring idle to normal after a couple minutes. If it dies it will stay open and give you permanent high idle. If it gets clogged usually no high idle for warm up.
You can remove it and peer through the end. If you see a thin sliver of light, it's open. Connect 12 volts + & -, wait a few minutes and see if it's now closed. If not, it's likely dead. It can be opened and cleaned if that's the issue.

Ideling up and dowen from 1000 rpm to 2000 rpm


Check your air inlet and vacuum hoses for leaks. Make sure the connections are tight. Normally it will be an unmetered air problem.
