Fuel Trim So I've got a v10 excursion with misfires on

Shameless selfbump.

I know what's wrong with it. It's a Ford! You know what they say Ford stands for, dontcha Hank?

It's my company's work truck so I didn't get to choose it. I just get the privilege of fixing it.

>>16276736
If they have high miles the v10 and
5.4 get shitty

>>16276943
It's only at 85k. I guess for a ford that might be a lot.

Spark, fuel, compression. It has to be one of those. Wires and plugs and coils are cheapest if you want to throw parts at it. Next you want to make sure the injectors are firing.

>>16276736
Check the plugs to see if they are coming out of the head.

I'm planning on starting with the fuel and air filters then some fuel system cleaner. Then checking the plugs.

Already done 5 of them with the timesert kit. I really hate the triton engine series. Im not noticing the smell of gas under the hood like I usually do when they are starting to go.

Problem identified.

No. Don't use any shitty snake oil products. There is an actual problem.

Fuel system cleaners work (the good ones)

>>16277237
There are plenty of legitimate injector cleaners grandpa. I'm not using marvel mystery oil or any of that shit. I use Lucas occasionally in my personal vehicle and like I said in the OP its at 160k and has an LTFT of 3.6. Which I would consider very good for it's age and miles.

Really you should change your oxygen sensor every 100k or so.
