FordEdgeeeeee Report post Posted February 25, 2019 I have a 08 ford edge sel awd. Has been great till now not sure what the issue is when changing gears i feel a slight bump been happening for about a 1month now. Also when driving or accelerating to a faster speed I get like a jerk or maybe like it's hesitant to speed up more i always feel the huge bump right under the car sometimes constantly for like a week then goes away for a few weeks, also when accelerating my tires feel like there not keep up with the speed like there not rotating properly it feels like bumpy then it'll stop if I slow down then the tires feel normal. I got my spark plugs changed thinking that was the issue with accelerating but it's continuing. I've taken it in to the shop to get diagnostic test/drive it but it didn't happen when they drove it so any suggestions would help greatly or if anyone else is experiencing this. i have about 166,000 miles on it. Ik it's alot. Share this post Link to post Share on other sites
WWWPerfA_ZN0W Report post Posted February 28, 2019 What is the maintenance history on this vehicle? Spark plugs, coils, PCV valve, throttle body cleaning, MAF cleaning? Also when were all of the fluids in the vehicle replaced, if ever? Share this post Link to post Share on other sites
FordEdgeeeeee Report post Posted March 8, 2019 I just had spark plugs changed getting a transmission flush next week then coolant flush was told the transmission flush was needed mostly. i get oil changes regularly and fluids topped off but have never changed coils pcv valve or the other stuff. I have no leaks or anything was told transmission is fine and not slipping. Should I get some of those things done? also do you think it could have anything to do with the transfer case gearbox which I'm also told can't be serviced unless the transmission is pulled out.

jroc2004 Report post Posted March 8, 2019 I had this issue on my 09 edge. When I changed the plugs the first time, I used ngk brand. It felt like a transmission shifting issue but it was not. I changed the plugs back to new motorcraft and haven't had the issue since. It was almost like a misfire but it was never bad enough to be detected by scanner with a misfire counter. Could be plugs, maybe coils. 1 Share this post Link to post Share on other sites
WWWPerfA_ZN0W Report post Posted March 9, 2019 I am a little confused (more than normal). Has the transmission fluid been completely changed or not? It should be. Coils should have been checked & electrically verified at the time the plugs were replaced. If they were not, they could still be a problem. MAF and TB should definitely be kept clean. I hope you have kept the coolant changed as well, to save the water pump/engine. Power steering fluid? PTU fluid and RDU fluid both can be serviced through the fill plugs they both have. Dealers may not do it (Ford policy on "lifetime"), but any competent independent shop/quick lube place/trans shop can do it.

FordEdgeeeeee Report post Posted March 9, 2019 Ok i see I'm not sure what brand the car shop uses or which one was in there before. From what I've just looked up seems like it could be my coils cause i have my own diagnostic thing which runs my car for error codes and nothing has ever showed up besides needing to change my battery. I'll change my coils and hope that resolves the issue thanks. Share this post Link to post Share on other sites
FordEdgeeeeee Report post Posted March 9, 2019 Oh sorry about the confusion, trans fluid has been completely changed before but has been awhile. I don't think they did check the coils but when doing the spark plugs they said all the wiring and hoses are fine. I've never done anything to the maf or tb so will get that done. I'm changing the coolant after my trans flush. Just had power steering checked and topped off. Haven't had my ptu or rdu fluid serviced. Ok thanks will check it out.
