Fuel filter could be plugged, or fuel injector is leaking. You can check fuel pump relay with an ohmmeter to see if it's good.

Ran it out of gas, now runs fine cold, as soon as its warm starts hard, and stalls when put in drive


Is the \'Service Engine Soon\' light on? Only from what you described, it sounds like the engine\'s running in \'open loop\' (fast idle, cold) okay, then when it\'s supposed to go into \'closed loop\', you have a malfunction. Checking the trouble codes will pinpoint the problem; your truck is pre-\'95 so it\'s the older OBD-I and you could get the trouble codes by grounding the proper terminal in the ALDL, counting the blinks of the SES light and using it to determine what electronic control device is malfunctioning. If no SES light/trouble codes and since you ran out of gas (?), it might be time to replace the fuel filter and possibly check the fuel pressure and/or fuel pump.

After starting the Check Engine light comes on and the cruise light flashes. Also the car will idle but not rev.


Impossible to diagnose without the trouble codes. Get the codes read and post here. ALWAYS start by reading the trouble codes to get a starting point.

My 96 Lumina, 3.1L has 94,000 miles and today during normal driving the service engine soon light came on and at idle the engine seems to be skipping or missing


If you know the plugs are fine then an ignition wire or a coil will cause the same symptom . If you had a code reader it would show you which cylinder is causing the miss. Beyond that a compresion test is needed.

Service engine soon light started flashing then started to idle erratically


It sounds like it could be the o2 sensors, the mass air flow sensor, or the idle air control valve, take the vehicle to your local auto parts store and have them connect their scanner and pull the codes.

What sensor do i need to disable to set timing on 1998 nissan frointer


well lets start with warming up the engine. so run it for a while. stop the engine and unplug the throttle position sensor. restart the engine and rev it 2000-3000 rpms 2 or 3 minutes under no load (such as lights, blower motor, a/c and so on) and then run it at idle speed. check timing at idle using timing light and set it to 20+/-2 BTDC.after adjustment shut the truck off and replug the throtle position sensor back. this will however turn your "service engine soon" light on, because you have unpluged the sensor and ran the truck. you will need to erase the ecm memory/reset it/get code reader and erase code.
thats how you doit without nissan scanner aka CONSULT2.

Hi, the Check Engine light and the cruise light blinking tells you the computer found a problem with your vehicle's running condition but if the vehicle is driving OK, a Check Engine light is not a reason to pull over and get the problem fixed soon. In testing areas, you will fail your emissions test if the Check Engine light is on and fuel economy generally suffers when the Check Engine light is on. When the Check Engine light is on, one or more "trouble code(s)" are stored in the computer and you can read and erase trouble codes using inexpensive code-reader tools from auto-parts stores; the tools are very easy to use. The problems identified by the codes are frequently easy to fix (such as a loose gas cap), but some are complex, requiring professional diagnosis. A trouble code indicates a circuit where the problem was identified, not necessarily the component itself. Diagnosis is often necessary.

Son let his car run out of gas, and when he filled it this code appeared with rough idle and stalling code 2002


I had a something similar to this happen to a girlfriend of mine. She has a 98 escort and it ran out of gas and the service engine soon light came on after she filled it up. If this is what your talking about check your owners manual. Most of the time if there is really nothing wrong with car you can drive it around ( Generally 20 min in town and 10 on the hwy with 4 idle periods (4 times of the engine being at idle) - do not cut engine off) and the light will go off. The rough idle code most likely happened when the engine ran roughly because. it was running out of gas.

Service engine soon is on and the truck idles low when cranked.


Take the vehicle to an autoparts store and have them use a scan tool to retrieve the fault code(s) stored in the computer. Most stores offer this service at no charge. The codes will help identify the problem. Sounds like a faulty Idle Air Control (IAC) valve to me, but the codes will narrow the reason down. Hope this helped and best wishes.

1994 Buick Lesabre service engine soon light. Can't read code.


I found several shops in my area, Albany, NY that had the older code readers. It worked fine, and cost me $30.00. It showed a bad O2 sensor that I replaced myself. I suggest you go to a reliable shop. Auto Zone/Advance etc.. do not have the right code readers. Joe
