Engine Coils?

[badbolr]

98 Mark VIII started acting sluggish and would die. When you start it back up it would go fine until the next time. Eventually becoming more frequent. Dealer says it is the "engine coils"?? I've never heard this term... an $800 job and 4-5 days. Sounds like they tear into the engine.

Any advice on this one?? HELP!

Thanks

engine coils are extremely easy to replace, I would check the boot on the coil first. Basically when you look at the engine you see a small cover with two bolts over the valve covers. Under that cover with the two bolts are 4 coils (one for each cylinder). They just pop out. When you pull them out, slightly bend the rubber boot on each to see if they are cracked and replace as needed. If its the coil you just unplug the harness going to it and replace it. Real easy job. I'd get the codes ran to see exactly which cylinder is mis-firing.

Engine coils

Thanks for the quick response! Unfortunately it is my sister's car and she is in LA and I'm in DC... If the job is so easy why are they quoting her 4-5 days. I think they said only 5 hrs of labor so that makes no sense. What do they do? I'm pretty much a car guy, albeit not a mechanic, but I've never heard of this part...

Thanks

The coils are p/n 4L7Z-12029-AA and they list for $64.29 each and cost you $39.06 each and include the boot. The boot can be had as a separate part and it is F7LZ-12A402-AA and it is listed at $17.37 and your cost is $13.03 each. On the mark it is usually the boot that degrades and on the LS it is the coil/boot assy that goes south.

GMS coils. More power, cheaper than stock.
