My Dad's 2002 F150 5.4 2v idles rough. I am wanting to know how hard it would be to take the fuel injectors out and clean them. Thanks.

 

what makes you think its the injectors? they rarely fail. I would think about new plugs and a set of E-bay coils. MAF and throttle body/IAC cleaning probably wouldnt hurt. heres how you can get injectors.

If cleaning them is what you want/need to do, it's not very hard. There is a how-to article somewhere out there (can't find it now) on exactly how to do this. You can buy a kit that includes 16 new o-rings plus a new filter that goes on the top of the injector. The process involves soaking the injectors in a cleaning solution, putting new filters & o-rings on them and reassembling. You could also run some fuel injector cleaner in a tank of gas (Gumout with Regane and Chevron's product are 2 that have been recommended) but I also suspect your problem is elsewhere. When's the last time the plugs were changed?

 

yea its probably something else, plugs probably

techron is also another good fuel cleaner

 

The plugs were changed with NGK platinum spark plugs at 180K. There is now 215k on the truck.

 

That leaves the coils @ 215k? Cleaning the throttle body IAC and MAF. If you do all that your truck will run better.

 

Techron *IS* Chevron's product. Another excellent fuel system cleaner is BG44K.
