Question type: Maintenance & Repair
My Mother In Law has a 99 Lincoln Town Car and she has had a bucking problem when she accelerates. The mechanic wants to replace spark plugs, boots, and ignition coils--over $1391 worth of work. The mechanic also wanted to replace the Intake Manifold, Manifold Gasket for another $1090. She doesn't have the money to do all this right now. The mechanic replaced 1 plug and 1 coil for over $200 and it's running great. I told her to just stop there but she thinks they know something we don't. I know how to replace the boot (coil on plug) & the spark plugs.

I found the boots (coil on plug) for $5.49 apiece and the ignition coils at $49.95 apiece. I'll check out rockauto.com though!!!

Wow, yup, they had them for a great price!!!
Well what is this an advertiser's forum to get people to buy things they may not need? First recognize that the 4.6 L V8 engine that is standard in the 1999 Town Car had an issue with the intake manifold that would crack and typically start leaking coolant. This is a a well known problem. All Ford, Mercury or Lincoln 4.6 L V8s made after 2002 model year came with a redesigned intake manifold that does not have this problem. If the intake manifold has never been replaced, this is a good service to have done, but shop around because it is not a particularly difficult procedure and any good mechanic can do this and replace the manifold with a newer one that will not crack. You forgot to state how many miles are on this vehicle. In the old days before platinum and iridium spark plugs were available it was common to change plugs at 30,000 mile intervals or less. When platinum plugs emerged in the mid 1980s the plugs could last much much longer.... typically being changed at 100,000 miles or more because the platinum allowed the plugs to last so long. As far as the need to replace all the ignition coils I have to ask, why? Ignition coils are quite dependable and diagnosing which one is causing any concerns is not difficult. For example on my 4.6 LV8 I have never changed the coils in nearly 24 years (the vehicle was built in June 1995) and the vehicle still runs smoothly! The mechanic already detected which coil is acting up and replaced it so why replace all the other coils? The spark plug wires (ignition wires) can also last an awfully long time as long as a mechanic is not fiddling with them by removing and re-installing the wires to the spark plug which can cause considerable damage to the wires (yanking on the boots and wires to remove them) because the conductor core (the part inside that transfers the spark to the plug) can be weakened by frequently pulling on the wires...it is typical for modern ignition wires on your 4.6 liter V8 to last 100,000 miles.
