It sounds like you may have developed a possible problem with the catalytic converters. They may have gone bad prematurely. If possible, since the emission light came on, you should have the vehicles computer scanned for codes. If you can drive the vehicle to an autoparts store they will do this free of charge. This will give us any codes to determine the actual problem. Also, if the problem is actually emissions related you may get it covered under warranty. Federal law requires emission systems to be covered longer then the original factory warranty.

Let me know,if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

    I took the car in and they said the car had codes P0191. Do you still think it is the converter?

    Thanks for your response!!

    The code normally means the FRP sensor is reading
    incorrect or the fuel pressure is actually dipping low under wide open
    throttle. You need to get an actual fuel pressure reading while
    duplicating the scenario which makes the light illuminate to see if your
    looking at a pump or filter or sensor.

    Let me know,if needed further assistance.

    Hope i helped you.

Periodic stalling after running for awhile . when the key is turned on no power to the fuel pump. After setting a few minutes key is turned back on there is power to the fuel pump and starts

The fuel pump only turns on for 2sec when key is turned on for a fuel pump prime. The fuel pump will turn back on during engine cranking. The most likely cause of stalling on this particular vehicle is a weak/bad crank sensor.

Hi. It would be useful to get a code read and some live data from a decent diagnostic tool. There are quite a few possible causes including, pressure in tank - if the fuel tank can't vent pressure then a vacuum will eventually form stopping fuel getting to the engine, this will cause it to loose power and stall. Then after a few mins the pressure will drop and the process start again, easy test is when the car stalls remove filler cap - if that's the fault there will be an audible hiss and the car will start up again.

part blocked exhaust will have same problems but will more generally cause a lack of power and acceleration.
are there other symptoms? i.e only when conering or only when pulling off or stopping, engine light on/off. Jon

My Jeep will cut out while driving and eventually go dead. After a bunch of restarts it will clear up. I've replaced almost all the sensors. Please help so it will stop

You need to test your alternator to see if it is properly charging your battery. Start your jeep and remove the positive connector from the battery. If your vehicle stalls you may need an new alternator. Also check the following issue that could cause you to stall, clogged fuel filter, choke not properly operating, faulty emissions system components, distributor cap damaged or wet, bad spark plug wires, leak in your vacuum system intake manifold or hoses. Also check your spark plugs for wear or improper gapping.

What is the function of lambda sond? it's good or bad ?it's about what?

First used in February of 1977 on Volvo B21 four cylinder engines, the Lambda-Sond system was an emissions reduction system which used three key components working together:-

1) Lambda Sensor. An exhaust gas composition sensor to monitor chemical composition of engine exhaust gases; especially NOx (oxides of nitrogen) which feeds data to the engine control system. In simple terms it's an oxygen sensor positioned in the exhaust pipe before the catalytic converter.

2) A feedback loop providing information to the engine control computer that enabled more precise control of the fuel injection system.

3) A catalytic converter.

This system greatly reduced exhaust emissions while allowing much better performance and fuel economy. It proved to be a key to restoring the performance lost by the addition of emission controls on vehicles. It was the forerunner to modern electronic engine management systems that eventually appeared as similar systems on all road-going vehicles.

So it's a very, very, good thing and like all similar systems requires periodic maintenance and repair, usually the parts which fail are the lambda sensor and/or the catalytic converter.

I hope that my speedy and free reply has met your requirements, if so then please take a brief moment to rate my answer.

1997 Audi died, lost power acts like bat dead but then starts?

the alternator is not charging and once you run out of battery power car dies when you let it sit battery builds a small charge enough to run short period of time.get charging system checked.

Turn the key on, nothing happen, no ligths inside nothing

1) Battery cables disconnected 2) Battery dead, probably shorted. Any other electrical problem, would leave some systems alive. A run down battery that wont turn over the engine, will still be able to power dome lights, or other accesories.

My 1998 acura CL stops while I am driving. It would start immediately but today i had to be towed to a repair place. What would it be?

have the ignition switch checked. When this happens does the speedometer drop to zero?? Is there some warning lights "not lit" when the vehicle stalls?? If yes to either of this, its a ignition switch failure. You may also try starting the vehicle(if possible) in the park position, and shake the key while engine is running, it should die(sometimes it may not even if the switch is worn). Hondas/Acura models years 97-02 were recalled in 2002 for this issue. The internal contacts in the switch encounter excessive arch/shorts due to poor design and too much power running through it. This causes intermitted power failure to vital engine/vehicle electrical components, causing the engine to shut down/stall. This progresses in hotter weather!! If this is the case, contact your local honda/acura dealer with your VIN# at hand for recall info and possible free repair. Otherwise the switches range from $45-$95 at advance or autozone. Hopefully this helps...please rate....thanks

95 taurus stalls out when temperature exceeds 102. The temperature gage seems to be in the normal range , when this occurs. Once car has cooled off, it drives fine. I have read that the 95 Taurus has had...

your evaprative emissions could be purging into the engine at that point too, giving too rich a mixture.

here's what you are referring to:

ISSUE: A reduced power, hesitation, stalling at low vehicle speed, idling and/or a no start condition may occur on some vehicles in hot ambient temperatures and/or high altitudes. In addition, a no start may result while the engine is still hot and the vehicle has been parked for a short period. A stall may also occur when moving the vehicle from idle. This may be caused by a lack of vapor ports in the fuel pump, resulting in a vapor lock condition or internal high wear of the fuel pump components due to tank contaminants.
ACTION: Perform normal diagnostic routines as described in the appropriate year Powertrain Control/Emissions Diagnosis Manual (PC/ED). If the condition still exists after all diagnostics are followed, replace the fuel pump with a new turbine fuel pump. Refer to the following Part Application Chart for correct part usage. Also, replace in-line fuel filter with a new filter (E7DZ-9155-A). The new turbine fuel pump will reduce the possibility of vapor lock in high ambient temperatures. Refer to the appropriate model/year Service Manual for removal and installation procedures.

the first place to start is the flashing engine lite. that means cylinders are not firing at all or improperly and driving it like that for even short period could cause heavier damage. particularly valves and cat converter(s) the computer really needs to be scanned for codes in order to proceed. did the oil lite come on before or after engine quit. after engine quit would be normal cause it stalled. its possible that it needs spark plugs and/or coils. or more
