I'm looking to print out instructions on how to change spark plugs. I have searched forums and found some old posts talking about doing it but links do'nt work when you click on it. I have watched the videos online but would be nice to have a reference under the hood while I'm doing this. Thanks, Wayne

Hello everyone.. Last week i did a 40k service at the dealership, and i changed the sparkplugs, they’re supposed to be motorcraft sp537, but instead they fitted sp578 into it, is that okay or would it make any problems to my ecoboost 2.0 engine?

Hey Guys, I know many forums require an OP in one of these welcome forums before you can post in certain topic forums so here it goes. just purchased my first FORD and so far I am amazingly pleased. 2012 Ford Edge SEL FWD 2.0L Ecoboost 116xxx miles Purchased for 10.5 which I thought was a steal. did my research and already knew about the common DOOR AJAR issue which I had replaced at the Dealer for about $300. but I got the dealership to knock off $500 for it so I felt very confident about this. i have put 2k miles on it since I purchased in early January 2017 and have had no problems since. I did however have a minor concern that I have noticed. and this might require moving this thread to another region on the website but i have been getting a little engine stutter since i had the spark plugs replaced at the dealership. i am not sure whether to attribute this to turbo lag or if the spark plugs may not have been seated properly by the dealership. this only happens around 1k rpm in first gear. any thoughts or info would be appreciated and I am sorry if this thread is in the wrong area. Best regards, B

Embarrassed but amazed, that I drove 220K miles on the original set of spark plugs. I have attached a picture of one of the 6, but they all looked identical. Maybe with electronic control systems this is expected, but the gap being over twice recommendation, and only about 10% of the electrode, let alone they were pointed (picture attached is of one of the 6, the other 5 looked identical). Gap on the original plugs was average 0.110. The vehicle ran okay, 21.4 mpg, I am hoping to see some improvement with the new plugs (also change the rear injectors, although they were replaced at 80K, only 140K on them. The front injectors have 220K). I have put around 500 miles on the truck since the change, and I definitely feel improved performance. Torque and Fillup (android apps) are showing some improvement on mpg, but will not pass judgement until at least I run through two full tanks. Interested in feedback, is this out of the ordinary, as I have heard that new systems with high quality plugs can go 100K?

Here is part 1 of a 3 part series.
