Your intake plenum(big gray thing) has 6 bolts. 2 in the front 2 under the plenum cover(thing that says 5.0) and 2 in the back. locate the 2 in the font and on the exact opposite side in the back you will see the other two bolts. Just behind it you will see it. there will be a bunch of hoses follow the biggest hose and just pull it. it should come right off from PVC valve. to replace it I suggest removing the hood and using a pair of pliers to pull it from the grommet. if you can hear it rattle its good. you may also want to replace the crankcase filter if its clogged. use pliers and a long screw to remove it.

Best I can tell you is that it is electronic. Check at your local Ford parts dept. They should be able to help you.

Check for fuel and spark - noting the age of the vehicle it may be the timing chain has "jumped"

Should be on the passengers side under hood, back of engine and fire wall. Look down.

Open the hood of the car and find the idle air control valve. The valve is located on the Gran Marquis' throttle body. The idle air control is a cylinder with a wire connector plugged into it. If needed, refer to your repair manual for an exact diagram.

Jump out the two contacts inside the switch body. I use a pair of tweezers, works great.

MY 93 GRAN MARQIS EGR VALVE IS LOCATED AT THE VERY REAR OF THE ENGINE BELOW THE INTAKE MANIFOLD AND A LITTLE TO THE RIGHT SIDE OF THE CENTER OF THE ENGINE AS VIEWED FROM THE RIGHT-FRONT FENDER. IT IS A LITTLE DIFFICULT TO SEE BECAUSE THERE IS STUFF OVER THE TOP OF IT. I DON'T KNOW IF THE 98 IS SIMILARLY SITUATED, BUT THAT WOULD BE A GOOD STARTING POINT.

Might be tough to do, but where the two lines go thru the firewall, join them together with a tube and clamps.

The o/d if left on will usually come on around 70 to 80 KMS ( 45 to 50 MPH ). Then the torque lock up will come on after that.

The entire light fixture has to be replaced. It is one unit. I assume lenses have yellowed. After-market available on e-bay, but expensive. You can try luck at a junkyard, but most are yellowed.

The 1996 Mercury Gran Marquis does not have a 318 V8. It has a 281 V8 (4.6 Liter). 318 is a Chrysler engine. O2 sensors are located screwed into the exhaust system. Start at the exhaust manifold and go backward and you will find them. The cost varies from site to site. Ask you local Auto Parts store for a price quote.
