Unhappy 2008 F 150 Ext. Cab 4X4

75K miles, work close to home .
Had tranny flushed @ 20K + 67K miles by dealership.....been feeling it downshift going up average grades for about 2 months
This morning it seemed to go in and out going up same grade.
I guess it's been 75% city - 25% highway driving since new.
I drive like I want it to last forever .
Any thoughts ?
sincerely and thanks

Have you changed the spark plugs yet? At 75k it's about time.

Sounds like you granny the truck.

I betcha you got a carbon problem going on.

First I would suggest running a bottle of Techron through your fuel and see if it improves.

If it does, I would then suggest doing what glc said about changing the plugs when you get some time.

75K is kind of early, but not really. Depending on how you use the truck.

OK, Techron is in.....called the stealership and they want $495. to replace the spark plugs.

They explained that @ the time my truck was built Ford was changing over from the plugs that were breaking(had black boots) to better plugs(had brown boots) that don't "break"

Current price to replace the black booted plugs $495. plus $50. for each plug that breaks

Price to replace the updated brown booted plugs $495. total

Just thought I'd share .

If you want it done right then forget using a dealership. You never know what Goober they'll never loose on your vehicle. Go buy some tools and a copy of the FORD shop manual and learn to fix it yourself. Experience isn't nearly as important as the determination to do the job right.

Watch this to get an idea what has to be done.

Take one of the coils off so you can see if you have the new one piece plugs or the older two piece that are prone to breaking. If the boots are brown, you have the newer one piece plugs. If they're black, then you have the older two piece design. That way you can at least know what you have.

The tag on the motor in the 08 F150 I picked up has a build date of 12-20-07 and has the brown boots. So if yours was built around that time or later, you should have the newer plugs in it and shouldn't have any problem changing them out yourself and saving over $400 in the process.

got the brown plug boots.....I lucked out

joe51, did my 88' Bronco plugs myself, they were easy.....we'll have to agree to disagree. If they had been the older spark plugs there's NO WAY I'd attempt them, unlike many guys on this website my "mechanical experience" is limited to oil changes, tire rotations, stuff like that . I'd rather pay and have it done right then attempt this by myself, buying tools that I'll find out I'll need and in the long run waste more than I would have spent hiring somebody with EXPERIENCE.

Fought fires in Philly for 39 yrs., in that profession experience is EVERYTHING.....I'd take 4 guys my age W-A-Y before 4 weightlifters with 34" waists and standing like Arnold Schwarzenegger

If you have the brown boots, just about any shop could change the plugs with no issues if you don't want to do it yourself.

I would talk with several shops until you find a mechanic that has done at least 1 set, and has the Lisle spark plug tool. I would read a bunch of posts and take some notes. Share those notes with the mechanic you find as suggestions. Lots of good info on this forum.
