I have a 97 wrangler 2.5. Check engine light is on, running lean, loss of power and high fuel consumption. I have replaced the o2 sensors, reset check engine code. light stays off and engine runs great for...

Something odd about what you posted. An engine that is running lean shouldn't be using a lot of fuel. Lean is when there isn't enough fuel going into the engine. Two other sensors that regulate fuel flow are the map sensor and throttle position sensor. Temp sensor generally would cause a rich condition but I'd test that too. Be sure to check for vacuum leaks at the manifold and lines as well as fittings... A vacuum leak will give the O2 sensor a lean reading...seeing that, the computer will try to compensate by adding fuel. Clearing codes can change the way it's running but as soon as the computer runs through it's internal diagnostics it will turn the light back on if there is a problem.

Vehicle running lean

I would want to know why you think that it is running lean. Did you get a fault code from the ECU stating that the engine was running lean? The O2 sensor registers the fuel mixture to the ECU and then it changed the fuel acording to your engine needs. Is the check engine light on with a fault code? I have had a few friends use the "sea foam" or the "lucas fuel injection cleaner" to help with the O2 sensor problems. I haven't tried it myself, but they swear by it. They are also mechanics too. Hope this helps.

Engine codes run on 2004 Freestar

Make sure you have all the vacuum leaks repaired.
Disconnect the battery for two mins,codes my clear.
The codes you got are O2 Sensors,because of the vacuum leak,which leaned out the readings and set the codes.

Check engine light is on..its chevy hhr, anybody can help please .and there was a code p2187

P2187-Fuel Trim System Lean at Idle--
If you have a cold air intake on your 2009 HHR turbo, it been know to happen. Your HHR is still under warranty so take it to the dealer, the code indicates that the engine is running lean when at idle but is running fine what engine is under load. It could be a simple update to the soft wear to the ECM to the HHR or a faulty MAF, regardless use the warranty you have and have them get your HHR running 100% again.
Thank you for using Fixya.

Check engine light keeps coming on. Lean fuel

A lean code can be caused by several different things. The most common, if you are getting a lean code on BOTH banks, is a dirty Mass Airflow Sensor (MAF) Cleaning the MAF usually fixes it.

If not, it could be caused by anything from a crack in a vacuum line to a bad fuel pump. (Anything that could make the engine run lean.)
