Tune up.

[ankles]

Hey friends,
So, i too am experiencing an occasional misfire and am looking into my options for fixing the problem. The way I see it is that I can replace all eight coils and plugs and start fresh, pay the dealer to diagnose the bad coil and then replace the one/s, or buy a scan tool for myself and diagnose and replace the bad one/s. I have read up on this problem on this forum and have heard that if one is going bad the others are soon to follow so it does not seem like a bad option to just go all the way with the tune up. All three of my options are going to cost me a pretty penny, but i feel that I will be further ahead if I leave the dealer out and go with the first or third option. What do you think?

P.S. I just got 26 mpg on a trip to seattle and back, around 520 mi. Not bad for speeding with a V8 and all. It was the best milage that i have posted so far. . .

I would take it to autozone and let them scan it since they do it for free. Then just replace the coils needed.

It is very difficult to diagnose a bad coil down to the cylinder. Honestly I would recommend replacing tehm all one side at a time. Do the plugs and VC gaskets if needed. The do the other side when you have had the chance to buy the new parts.

You can do the job if you have some basic tools the thing to decide is whether or not you want to redo the disassembly/reassembly multiple times if you discover another coil has gone bad.

Hi, I would start with the simple things first & ( least expensive). Sparkplug & make sure no corrosion. Assemble with dielectric grease.

I got price quote from Max at five star and he said that he could get me coils for around $56 a piece. The cheapest I have found them is $39 for some ACDelco parts at rockauto.com, Has anybody found a better price? from my reading i see that many of you recommend the motorcraft parts for reliability and current revisions, but $56 x 8 = lotta dough. Thank you for the reminder to start simple ls-steve, makes lots of good sense. BTW i live in a small town with no Autozone or other store that will read my codes for free, which is why i am considering either buying my own reader, or simply putting the money toward the tune up parts. Havta move to the big city where competition is fierce. . .

Are the coils covered under ESP?

I didn't know that they did that. What all can they scan for?

 

[eL eS]

They can only scan for active DTC's and maybe pending. They will not be able to identify which cylinder is misfiring unless it has thrown a DTC.

sorry to ba pain newb but i search and didnt find an answer, although the premium care brochure would leave me to believe they are covered.

Any one had any experience getting Premium Care ESP to cover replacement. Went to change spark plugs this morning, and 3 of 4 coils on passenger side had oil in them, car has been hesitating lately, but no check engine.

Also has anyone considered trying to start a class action, might be able to get ford to ammend the standard warranty for the LS to cover COPs for 125K ect.

Hey I work at a dealership and if you have premiumcare, and need to know if the coils are covered call me at 775-824-3409 on mon. and give me your vin and the base part # and i can look it up for you.

I sell them for $37.00 a piece. In standard. Still pretty pricey if you buy all 8 tho.

Dealership told me the coils should be covered, but they wont replace them just because there is oil on the boot (without a code, or if they can verify that it is defective), but they will replace the gasket. Also said it doesnt matter how many are bad they are only authorized to replace the defective units (I guess make sense from a warrenty perspective).

I've got an appointment for next monday, but I was under the impression from the board that oil on coil=bad coil?

Yep, when the coil gets wet, its ruined. I had 74k miles when I needed the COPs replaced, I will definetly join in on a class action with that problem!
The Dealer wouldn't just replace the bad coils, they only replaced all of them. The reason they gave is that when a coil goes bad it makes it harder for the other coils to work, which damages them. I told him that the problem is a Manufacturer defect and should be covered under warranty - he said nope. Oh and I got great mileage while the COPs were bad, you're not using all 8 cylinders when that happens. Get it fixed you'll notice a huge difference!
Cost me $2k. :L :give

Makes sense when the dealer think it going agianst their warranty record, they will only replace the bad... But when the consumer is paying for it, they will only replace them all.

I just bought a navigator off this dealership, so they better make right by me or it will be the last vehicle I buy there. Although short of the navigator there is nothing in the Lincoln lineup that even interests me (unless we see a very highperformance LS type vehicle, a cts-v killer).
