Chevy 2002 Malibu ERG valve


Symptoms of a bad EGR valve are usually stumbling idle or the engine stalling when the car is warm (normal operating temperature). Find the EGR valve and locate the vacuum line attached to it. Start the engine cold and wait for it to warm up. When the engine starts to stumble, pull off the vacuum line. If the EGR is bad, the engine idle will stabilize and no longer stumble.

Smokes at idle, not while driving.


you have hit the nail on the head ,starting a cold engine and just leaving it to idle takes a while to warm up ,but driving it straight away which is what you should do get the engine warm quicker ,also reduces your carbon footprint.When the engine is cold it burns oil till the correct clearance and tolerances are reached .

We have a 1990 lebaron 56000 miles when it gets cold outside,like35 degrees sometimes the headlights will not go on until after the car is fully warmed up. the hi beams will always work but the headlights...


the old chryslers were very suseptable to dampness esp at 35 deg after car warms up the damp wires would dry off and the problem would go away some time this also affected the ignition and car would not start on damp or rainy days as well

Just got a 1990 olds cutlass suprime.has the3.1 v6.car has set outside for 1 year and not run.has trasmission leak at the pan.plan on replacing fiter and gasket.how much fluid does it take?car runs rough...


Just changeing the filter and gasket, you shouldnt need much more than 4 liters (1 gal) just keep checking and dont over fill it.

as for the rough running after warm up. could be mass air flow sensor, to test, when car warm, tap the sensor wiht the handle of a screw driver when its running.. if it stumbles or stalls when you tap it. then it needs to be replaced. it could also be coolant temperature sensor, or leaking EGR valve.

WHERE IS THE EGR VALVE ON A 1990 OLDSMOBLE CUTLASS SUPREME LOCATED AT


6ff5ad5.jpg About $140.00

The EGR valve is mounted on the intake manifold and has an opening into the exhaust manifold.

The digital EGR valve, used on all 1990 and later EGR-equipped engines (Except the 2.5L and 1994-96 3.8L engine) is designed to control the flow of EGR independent of intake manifold vacuum. The valve controls EGR flow through 3 solenoid-opened orifices, which increase in size, to produce 7 possible combinations. When a solenoid is energized, the armature with attached shaft and swivel pintle, is lifted, opening the orifice.
The digital EGR valve is opened by the ECM, grounding each solenoid circuit individually. The flow of EGR is regulated by the ECM which uses information from the Coolant Temperature Sensor (CTS), Throttle Position Sensor (TPS) and Manifold Absolute Pressure (MAP) sensor to determine the appropriate rate of flow for a particular engine operating condition.

Digital EGR Valve Testing:

This system must be checked using a Tech 1®or equivalent scan tool. Steps 4, 5 and 6 must be done very quickly, as the ECM will adjust the idle air control valve to compensate for idle speed.
  1. Using a Tech 1®or equivalent scan tool, check for any diagnostic trouble codes and solve those problems first. Refer to the Diagnostic Trouble Code (DTC) lists later in this section.
  2. Select "EGR CONTROL'' on the scan tool.
  3. Start and run the engine, until it reaches normal operating temperature, then allow the engine to idle for 2 minutes.
  4. Energize EGR SOL #1; engine rpm should drop slightly.
  5. Energize EGR SOL #2; the engine should have a rough idle.
  6. Energize EGR SOL #3; the engine should idle rough or stall.
  7. If all tests were as specified, the system is functioning properly.
  8. If not, check the EGR valve, pipe, adaptor, gaskets, fittings, and all passages for damage, leakage or plugging. If all is OK, replace the EGR valve assembly.

1990 chrysler lebaron goes into limp mode have to stop car restart and problems stop temporarily


The symptoms you describe, "limp mode", no check engine light, after a restart you get a temporary cure, and the year of your vehicle, tell me your catalytic converter is becoming clogged.

As your vehicle warms, the exhaust pressure builds and can't properly escape through the catalytic converter. When you turn the vehicle off, the pressure slowly releases, and when restarted it will run ok again until the pressure builds.

I would replace the catalytic converter, and that should resolve your issue.

I hope this information helps you, and I wish you luck on your repair.

Egr low circut malfuntion


  1. Check the EGR control system and EGR valve with the engine fully warmed up and running [engine coolant temperature over 76 °C (170 °F) ]
  2. With the transaxle in neutral and the throttle closed, allow the engine to idle for 70 seconds .
  3. Abruptly accelerate the engine to approximately 2000 r/min , but not over 3000 r/min .
  4. The EGR valve stem should move when accelerating the engine. Repeat the test several times to confirm movement.
  5. If the EGR valve stem moves, the control system is operating normally.
  6. Remove the vacuum hose from the EGR valve and plug the hose end.
  7. Connect a hand vacuum pump directly to the EGR valve
  8. Check whether the engine stalls or if the idle is unstable when a vacuum of 20 kPa (6 in.Hg) or higher is applied while idling.
this is the test procedure but I would suspect the EGR TRANSDUCER SOLENOID
