My 2000 ls has the check engine light on. It reads lean and i replaced both front 02 sensors but light still comes on. The car runs fine but turns off at idle regardless if in drive or park. HELP?
Since you didn't mention the make or model of the vehicle, you will have to look at the following... A lean O2 sensor does not usually mean that the O2 sensor is bad. Since your idle is bad, you need to look at other air/fuel controls such as EGR, MAF, MAP, IA, injector nozzle and anything else that would either restrict air or fuel at idle
Your 2000 Lincoln ls V6 has the check engine light on It reads lean and you replaced the fuel filter but light still comes on The car runs fine but turns off at idle regardless if in drive or park?
You have replaced the O2 sensors in your 1998 Mercury Mystique how do you reset the check engine light w no diagnostic scanner?
2001 Pathfinder engine light problem you replaced 2 oxygen sensors then replaced 2 timing sensors the service engine light still on computer shows no code?
Wrong scanner?? If a check engine light is on, there are codes. Timing sensor? Check engine usually means a problem... Service means that scheduled service needs to be performed like oil change, or timing belt replacement. I would Check your Catalytic Converter. What often happens is the catalyst that is in the Catalytic converter Heats up and Blows out into your Muffler. This means It is not the sensor,but your converter and Muffler Need Replaced.I…
Maybe the sensors you changed out were not the problem. Post what the symptoms were, what the codes were, and why you changed out what sensors you did. Sometimes errantly the wrong part is diagnosed as being defective, like having low fuel pressure and people spend $500 for fuel injectors when in reality it was a clogged fuel filter for $10 Some cars take a few starting cycles or cycles of driving before they reset…
Why is a 2002 Mazda mpv check engine lite coming on when all 4 sensors have been replaced car and the car seems to be running fine?
the check engine light could stay on because of other sensors. for example,the power steering sensor could be bad...this will cause the engine light to come on and other sensors could cause the engine light to come on. just get rid of the van. most sensors when they go bad cost anywhere from $200-$600 just because of the location of the sensor. manufacture put sensors in hard to reach places to keep you from replacing…
What could cause a 1999 Toyota Camry check engine light to come on after replacing all the sensors and driving it for about forty miles?

I have a 1995 Ford Taurus that runs fine but every time you hit a big bump the check engine light comes on for a few minutes then goes out what is happening?
If a 2001 Chevy Impala LS check engine light is on and the diagnostic says low emissions but you replaced both O2 sensors and the air filter what else could be wrong?
Your car has a number of places where leads attach to sensors. Those sensors go to a computer. When one of those sensors goes bad or gives a bad reading, the check engine light appears. It means something is wrong somewhere with your car. They can attach a computer to your car's computer and find out where.
How do you reset the brake pad wear warning light on a 2008 dodge sprinter after replacing the pads?
Your o2 sensors are on the exaust manifolds, if you slide under the truck with a flashlight and look up at th manifolds were they come out of the engine you will see each manifold has a sensor, also check with your Toyota dealer, because there was a recall on these sensors that melted in to the manifold. They replaced mine for free.
