Is it true you really have to change the spark plugs Ford F150

Is it true you really have to change the spark plugs on a 2004 F150, 69K miles? I just paid $415.00 for this mechanical problem I was told I should do as if these sparks plug break off it is twice as expensive to fix the problem...

    Thanks for the info as Goodyear told me it was recommended on my 2004 F150 at 60K

    Well that just figures, I guess the struts and shocks they recommended are not needed either. My truck only has 69K miles and I take care of it servicing it every 5K miles.

As the tech says, recommended is 100k, but I had to change mine at 83k as the engine was starting to miss (stutter). I did it myself and saved $300 in labor. Stutter disappeared after I changed them out. The two in the back are the toughest.

    they don't know what they are talking about, they are just trying to sell un-needed work, that is a very expensive tune up, about 2.5 hours of labor.. Ask them to show u the Ford technical material that says 60,000 on the plugs. My Father has a Ford truck with 200,000 plus miles the spark plugs are orig and it runs like a swiss watch, not saying u should do that, but just wanting to show that changing them early is a huge waste of money in a dismal economy..

97 Ford F1 54.6 V-8 starts missing at 60 miles an hour will not go any faster


Go to almost any auto parts store, and have them run a diagnostics on it. They all do it for free these days. Could need one of the throttle body sensors, ie ~ MAF, AAF, Vacume Idle sensor, etc. Other than that there are the tried and true problems, spark plug electrodes worn completely down, replace plugs. Fuel filter clogged and never been changed. Plugged catalytic convertor.

Adjust idle


Before i would adjust idle i would first check the timing. It should idle at or around 750 rpm. Secondly depending on how many miles you have put on the spark plugs i would also consider changing them. Changing spark plugs i a time consuming job. The ladt two plugs neareast the firewall are really hard to get out and when you put the plugs back in use a plug lubricant for the threads.

When do spark plugs need changing


Ford recommends 100,000 miles on the original plugs. That is ok to do as long as it isn't missing or giving you any indication that they need changing. I hope this helps.

Is it true on 5.4 06 that you need a special tool and only ford can change the spark plugs


Yes it is true.

The special too is to remove a broken spark plug.

It is not recommended to do anything to the spark plugs until 100K.

RECOMENDATION:

If your not a mechanic spend the money go to the Ford dealer and let them address this issue.

It will be worth it not to need to pay for a tow truck.

Hope this tip helps.

What is my maintenence schedule ?


I woud replace the fluids,including the brake fluid. Be sure to use the correct fluids, follow the FORD specs. Yes the spark plugs are a big issue. Be sure the mechanic knows what he's doing, if not, have the Ford dealer replce them, Special tools are involved because the end of the spark plugs break off in the head and they will need to be removed. Expect to pay BIG BUCKS. This alone is the reason I will never own a Ford Truck.
