Well, if you have owned the vehicle since you got it, you would have known how old each one was, as it is, I just purchased this one with 180k on it, and they all are probably the stock ones, which means each one will probably fail in the near future. And since the dealer charges such an enormous fee per hour, why not get them all replaced at once? and save all the extra fee's? I could also buy the cops on ebay and have a local auto repair put them in for probably about half the cost.

 

changing the COPs isn't hard to do. If you want to do it all at once, then do it. I was giving you my opinion on what I would do. I bought my truck 4-5 months ago (2001 F150 Screw 5.4 with 128k) and I didn't know the history of the truck, so I had the plugs changed, but not the cops. If one goes bad, I'll replace that one. not all of them at once. Our f150s tend to have problems with the cops going bad, so why not just fix the ones that are bad, and keep the others for spare for when another goes out?

 

Sounds like the intelligent thing to do, i'll order a set off ebay, run the obdII, find the plugs and if I cant get to it, i'll ask a local mech to change it out.
Thanks for all the input I really appreciate it!

 

No problem man, that's what we're here for. Hope all goes well

 

Now, the still unanswered question i've had...the manual tells me I have to remove the fuel rail to get the coils and plugs out, do I really have to?....sigh... cause if I do, i'll go ahead and buy all new orings for all the fuel injectors.

 

I remove the fuel rails just to give me more room to get to the plugs. A dab of engine oil on the injector O rings and they are as good as new. I try to leave them in the manifold but some times they pull out. It just makes less of a mess to clean up. By staying in the manifold there is no chance of dirt getting into the hole.

 

I got the set of 8 Accels from Amazon.com for $165. I replaced the bad one (#6) and put the rest on the shelf in garage for future needs.

 

I know I need to remove the rails for #7, or really fight getting to the plug. May try with the u joint and extensions, but only if I can find the duct tape and tape everything together. Hubby had a PIA time with a couple plugs when the extensions kept coming apart and leaving the socket behind.

I think that mechanic was thinking coil packs not cop's. Not a good sign.
