Why do my engine rattle and lose power when driving up high bridges?

Thank you Sir! The auto parts couldn't check because I have no engine light on.

These are usually the problem with your symptoms, not always turn the light on.

Thank you for helping me Sir !

U Bet

Are you serious; where did you come from, and how many cars you worked on still run.

the same problems/symptoms happened on my nephews 2000 grand am, he had loss of power going up hills and the car would stall randomly.

You need to go back to school, are you the one with Fords, and don't know the fix for these symptom? Just answer your own questions and I'll take care of the ones I answer, Bless Your Heart.

well then, I'm at a complete loss maybe you can answer this question, I have two plugs from the front of my expedition, 1 is for the heater core and the other I have no idea??? I've searched every forum on expedition/F150 and I also went through all three manuals and their is nothing, and yes I am the one with the "Fords" I run duel monitors so when I come across this site I was looking to finds answers from another angle bc when I comes to different makes n models their really is no 1 answer more less multiple answers. and as for Ford's in general they have what's also known as "phantom problems" were 2 identicle problems will have different solutions. and with power problems you can normally trace it back to the ground, weak or loose ground are the same thing. and yes "phantom Ford problems" look it up

First of all, I really can't stand Fords. I do make some really good money fixing them, and as the saying goes, If it wasn't for Ford's, I'd go broke. As far as plugs at the front of your Expedition, My definition of a plug has many possibilities. I assume your might be referencing a 120v type plug, like for a block heater, but I'm not looking at it, you are and I really don't care what it's for. I didn't install it, and I'm not working on it, and I have never paid any attention to plug in's unless the vehicle has been presented to me for a fault that might concern an issue with it. As far as your summary about Phantom problems, and the same symptoms are not always the same fault or fix. I have learned these things over 40 years ago, and have not forgotten them, because we deal with them day in, and day out when all you do is work on vehicles, fixing customers problems all day at least 5-6 long days a week. I learned something a long time ago when I was in the Marine Corps. When your trying, as a younger man, to be a person thinking of ways to cut corners, or make yourself look good to someone who has been doing something a lot longer than you have, and they can come back and tell you what you did wrong, or even why you did it, what ever that may be. It's because they have already made the same mistakes, thought the same things, and walked in your shoes. So to try and explain something to you, I have already been through all the things you have been through, and probably more times. I have forgotten more than you know, and I am still learning things you haven't even thought of yet. Let me politely say; Sometimes it's better to listen then to talk and show how much you really don't know. It's been great talking to you, but enough is enough.
