Question Answered: 

Those coil packs are VERY common failures in ALL OHC Ford V8s and V10s. Do it now, and save yourself alot of trouble. The labor cost for 8 isn't much more thn for 1, unless you do them one at a time.

Question Answered: 

A faulty Idle Air Control valve can vibrate wildly, and will cause that noise. Ford V8's and some V6's will do it, and it is not an uncommon problem, but it does happpen more in the V6's.

Question Answered: 

This is a common problem with OHC V8 Fords. Some suffer more than others. There only a few acceptable repairs for this, and Helicoil is not one of them. If you tried a Helicoil, it will not hold properly in a 4.6. There are other solutions that are much more reliable. They are fairly expensive, and a shop that has the can probably take care of it for you for less than it would cost you for the kit, providing the head is still able to be repaired.. There is a TSB for this condition, and it changes regularly to incude different repairs, but it is always animate on not using Helicoils.

This kind of fitment problem is not uncommon with aftermrket parts, and header panels are notorious for fitment problems from the aftermarket. If you can tolerate the look, than fine, but a used panel from a salvaged P71 might solve your problem.

The Air Bag lamp will not illuminate for maintainance. If it's on, there is a fault in the system that only a shop can scan and find.

Question Answered: 

If the code is insufficient flow, your car needs to be scanned at a shop to verify the DPFE sensor is working properly. this sensor is a coomon failure in OHC Ford V8's.It shoud read about 1 volt DC with the key on and the engine off. If it reads lower, or near 5 volts DC, the sensor is faulty. The older 4.6's did have problems with clogging EGR ports, but that was long solved by 2001.

Question Answered: 

There is an active TSB for this condition. It is caused by metal debris that is stuck between the head and the block. It is fairly uncommon, and it is not a warranty condition any more. Head gaskets on any 4.6 are no fun, except for me, but if it is leaking from there, that is your only choice. It could be a valve cover, as well, but while easier, they are also alot of work on Grand Marquis 4.6 V8s.

Question Answered: 

that is not a simple repair on a GM, especially on the right side. You would be better off taking the car to a shop to confirm what the noise is. A timing chain can also make that kind of racket, and is a much easier repair.

Question Answered: 

One of the air bags has probably failed. The problem is the air compressor will run continuously trying to fill that bag, and will also soon fail. There are kits available that have both bags, and a compressor for about $400. There are also kits available to convert the suspension to standard coil springs, and eliminate the airbags all together. Either way will solve your problem, as the airbags have come down in price, and are easy to replace in a shop enviroment

Question Answered: 

It most likely is the air bag that has failed. Theses replace the coil springs on some of these vehicles, and are designed to keep the vehicle level when the car is loaded.They are not overly expensive or difficult to replace by themselves, as long as the small air compressor has not been damaged from running constantly trying to fill the failed bag. There are entire kits available that come with both bags, and a compressor for about $400.00. There are also kits available to convert the springs to standard coil springs, and eliminating the air suspension all together. The easiest way to tell if you have air suspension, is to look athe the label on your drivers door. On the bottom of that label, if you see 65ZZ, 32XX, or 76ZZ under the SPR, then you have air suspension
