Adam Harush Posted January 11, 2016 Report Share Posted January 11, 2016 Hey I have a Ford Edge 2012 3.5 6 cyl Lately, I have problems with rpm While stopped at a traffic light, the vehicle starts to stutter, and little vibration, I wanted to know if it is because the throttle, or oxygen sensors, (Sometimes pungent smell outside the driver's side car) Vehicle traveled 110 thousand kilometers I'd love to answer thank you very much friends Quote Link to comment Share on other sites More sharing options...
macbwt Posted January 11, 2016 Report Share Posted January 11, 2016 O2 sensors would throw a code. Your cat could be damaged due to a rich fuel mixture. I however would suspect the Throttle body. You may wish to clean it out good with some Throttle body cleaner. Low cost item to check and clean and easy to do. Worst case the TB is not working correctly.

WWWPerfA_ZN0W Posted January 12, 2016 Report Share Posted January 12, 2016 Any warning lights on the dashboard? Any codes set (they can be, even if there is no Check Engine Light)? When was the last time the air filter was checked/replaced? Same question for the MAF sensor. Quote Link to comment Share on other sites More sharing options...
Adam Harush Posted January 12, 2016 Author Report Share Posted January 12, 2016 Two weeks ago ignited lamp engine, and the computer said code P2196 P2198, and once went P0196 P0198, I realized that oxygen sensors or sensor temperature of the oil, currently not turned on after resetting, but there are still tremors and fall prm while standing at a traffic light, what do you think, is clear Throttle ? Is every 100 thousand kilometers replace oxygen sensors? Thank you, I'd love to answer the problem Quote Link to comment Share on other sites More sharing options...
WWWPerfA_ZN0W Posted January 12, 2016 Report Share Posted January 12, 2016 There's no set time interval for O2 sensors, but 100,000 MILES in the U.S. is a reasonable interval for O2 sensors if you wanted to do preventative maintenance. In the Middle East, not sure what the appropriate interval would be, due to different environmental conditions (heat, sand, etc). So check for frayed wiring, dirt intrusion into electrical connectors for O2 sensors and oil temp sensor. I'd have the evaporative emission purge valve checked for leaks. Similar to what this TSB for the Escape/Fusion says to do: http://www.revbase.com/BBBMotor/TSb/DownloadPdf?id=173431 Keep in mind that if your Edge is on the original battery, it might be time for a heavy-duty replacement. Assuming the same battery sizing in the Middle East, consider upgrading to a Group 65 battery. Worn batteries can set all kind of false alarms, and cause sensors to react inappropriately (voltage regulation). An alternator/generator check should be performed at the same time. If the battery is being replaced, have the Battery Monitoring System reset so the PCM recognizes and charges the battery properly. Quote Link to comment Share on other sites More sharing options...
Adam Harush Posted January 12, 2016 Author Report Share Posted January 12, 2016 Thank you for the wonderful response, today I cleaned the throttle, looks fine, do I still have an interest to replace the oxygen sensor or the maf, even that warning, or simply waiting for some sign or a kilometer higher?

WWWPerfA_ZN0W Posted January 12, 2016 Report Share Posted January 12, 2016 I would still clean the MAF sensor with MAF cleaner (do not use brake cleaner/carb cleaner etc). Then wait for driveability symptoms and/or codes to reappear. Definitely recommend having the battery evaluated with a digital CCA tester.

Adam Harush Posted January 17, 2016 Author Report Share Posted January 17, 2016 Hello friends, I wanted to ask why every time I refuels the vehicle, start it first he can not start, only the second time he came on, they told me because after refueling nozzle of the gas not close like a vacuum?, Is this true and if anyone knows the reason I'd love to answer Thank you very much.

Adam Harush Posted January 17, 2016 Author Report Share Posted January 17, 2016 My question refers, after refueling vehicle! Quote Link to comment Share on other sites More sharing options...
enigma-2 Posted January 18, 2016 Report Share Posted January 18, 2016 Is it "only" after you refuel or does it also happen after the car has been sitting overnight? Personally I doubt it has to do with a "vacuum" problem, probably more like the fuel line is not remaining pressurized. Who were you referring to as "they"?

Adam Harush Posted January 18, 2016 Author Report Share Posted January 18, 2016 Only after refueling, after a full night everything is fine? Quote Link to comment Share on other sites More sharing options...
WWWPerfA_ZN0W Posted January 18, 2016 Report Share Posted January 18, 2016 Capless fuel filler system, right? It's possible that dirt has builtup in the fuel filler neck area, making the spring slow to return to original position. A careful cleaning may be all that's required, or if it's bad enough, you may need to get the filler neck replaced. Quote Link to comment Share on other sites More sharing options...
Adam Harush Posted January 18, 2016 Author Report Share Posted January 18, 2016 I thank you for the answer, I soon will review the tip you gave me, and come back with an answer, thank you very much friend Quote Link to comment Share on other sites More sharing options...
Adam Harush Posted January 28, 2016 Author Report Share Posted January 28, 2016 Peace About oxygen sensors After I cleaned the throttle, do not turn on the light bulb of the sensor, and now after a month, refuel the car and immediately kindling once again I turn on the lamp, is there a connection between the fuel and the oxygen sensor? Quote Link to comment Share on other sites More sharing options...
WWWPerfA_ZN0W Posted January 28, 2016 Report Share Posted January 28, 2016 The oxygen sensor essentially helps the PCM figure out how much unburnt fuel there is in the exhaust, and the PCM then adjusts the air-fuel ratio accordingly. This is a continuous process as you drive, not a set-and-forget. That's how the vehicle can achieve the greatest fuel efficiency. Except at WOT, where a relatively fuel-rich mixture is run for maximum available power while preventing engine detonation/failure. Each time you fill up gas, the engine will evaluate fuel trims (air fuel ratios), and can take a few miles of driving to settle into a steady long-term situation (the "new normal"). This is a more pronounced effect in the 2011+ because the PCM adjusts engine performance based on the fuel quality. 2007-10 PCMs do not. Are you are getting fuel from the same station, maybe the fuel is not very good - change stations and see what happens next time. Check & clean the throttle body again, see if the light goes out again. If so, there could be a PCV related issue. Make sure you are running the correct engine oil, and clean or replace the PCV valve. Did you have the exhaust system checked for leaks? Can be very small and hard to find.

akirby Posted January 28, 2016 Report Share Posted January 28, 2016 If the fuel is bad it could cause a misfire. What code are you getting now? Quote Link to comment Share on other sites More sharing options...
Adam Harush Posted January 28, 2016 Author Report Share Posted January 28, 2016 I have not managed yet to check, hoping the morning to go to a mechanic that will connect your computer, is there another way to know? Quote Link to comment Share on other sites More sharing options...
Adam Harush Posted January 28, 2016 Author Report Share Posted January 28, 2016 Many thanks for the detailed answer, I will check the information you wrote Quote Link to comment Share on other sites More sharing options...
WWWPerfA_ZN0W Posted January 28, 2016 Report Share Posted January 28, 2016 You can get an OBDII adapter that you can monitor on a mobile device like a smartphone or tablet or even a Windows PC. Software like Torque Pro (Android devices only) or Forscan (Apple & Android devices, Windows PC) can read codes from the computer. In the U.S., auto parts stores will read the codes for free, but I don't know what the setup is in Israel. Quote Link to comment Share on other sites More sharing options...
Adam Harush Posted February 3, 2016 Author Report Share Posted February 3, 2016 Hello friends I am waiting to receive the OBDII adapter After I turn on the lamp of the oxygen sensor, Refuel my car fixed station And the lamp going out ?! Is there a connection refueling going out lamp? Can I clean the throttle, without dismantling the whole, clear through the window? And if a material cleaning? While the bulb was lit, smelled acrid exhaust, and rpm was playing, now there is no smell at all and rpm is not a game! What does all this mean?

Adam Harush Posted February 3, 2016 Author Report Share Posted February 3, 2016 Now my friend, did not come on the lamp, and have not received the Obd2, I look forward to it, and soon I will inform you what the code? Quote Link to comment Share on other sites More sharing options...

WWWPerfA_ZN0W Posted February 3, 2016 Report Share Posted February 3, 2016 Many Ford dealers have online stores you can buy from. If you go to levittown ford's site (they are a sponsor on this forum), you can get discounted pricing on parts. Plus I believe they will ship overseas as needed.
