pamx Posted August 12, 2009 Report Share Posted August 12, 2009 (edited) I own a 2008 Ford Edge, which currently has 35,000 miles. Recently I noticed that my idle speed is fluctuating about 500rpm. I first noticed it after completing a 260 mile trip and associated it with the A/C being on. After shutting A/C off, I realized that the A/C just made it more noticeable but it was still there. When stopped at a light, the rpm drops from its usual 600rpm's to about 400 and then increase to about 900. Problem is fairly constant once the engine warms up, about once every three seconds. I don't see the problem when engine is cold. I think I can feel rpm changes while driving as well. Any ideas?

I told them that the one in it was new but they insisted it was now corrected. Problem still there. Bringing it back for service tomorrow.

BlazedUp Posted August 23, 2009 Report Share Posted August 23, 2009 Sounds like a camshaft position sensor issue. My idle would jump up and down stopped with foot on brake. I believe this went on for a week or so before the check engine light came on. Camshaft position sensor is a known issue with these cars.

Sounds like it could be the Electronic Throttle Body, but without seeing the car and checking it out myselft, that is just a guess. Quote Link to comment Share on other sites More sharing options...

Just curious, since you have the repair manual and any moron and fix a car, how would you go about fixing this concern. Do you also have an IDS, you must, since you have it all and know it all.

BlazedUp Posted August 25, 2009 Report Share Posted August 25, 2009 I was simply stating that we had a similiar issue. Foot on brake and idle would fluctuate. I was just offering a possible solution, since the dealer replaced a clean air filter hoping the problem would dissipate into thin air. I never intentionally post "wrong" information and I do not know why you get your panties in a wad Druck. This was not directed towards you, nor was this thread. I am here to help, and I thought you were too. If you have nothing better to do than to troll, I suggest you look up the IDS because it is not available in the on-line repair PDF. If you have nothing good to say, or no help to offer don't bother to post. Also, the oasis database has this issue noted, but I am sure you already knew that Quote Link to comment Share on other sites More sharing options...

pamx Posted August 28, 2009 Author Report Share Posted August 28, 2009 Appreciate the input. Just got it back from the dealer and they replaced the electronic throttle body. It appears to have fixed the problem and in all honesty it feels much more responsive. The dealer said that Fords Internal Hotline suggest changing this unit for almost any kind of idle problem and that Ford has had to replace a bunch already.

druck52 Posted August 29, 2009 Report Share Posted August 29, 2009 Seems like this bully and troll was right about the throttle body being bad. Just glad that she got the problem fixed. Quote Link to comment Share on other sites More sharing options...
