#36 of 102 Re: 1998 Mercury Grand Marquis Checkup? [gobig] by captainkirk1 Jul 18, 2006 (7:07 am)
Replying to: gobig (Jul 17, 2006 8:10 pm) Dear Gobig,   Nice to hear of someone else close to my situation....my purchase was of a '94 MGM GS with only 23k on it. I replaced the wiper blades, brake pads, and flushed the coolant system myself. I took to the dealer to have them flush the transmission. It had that stuttering vibration at 52mph because the previous owner didn't use the proper fluid when he changed it. The flush took care of the problem. I live in FL with hot humidity and am weary of anything rubber as I can tell by touch it is rotting. I also dealt with a leak. Everytime we get a bad rain, the right rear of the car fills up with water. I've taken the floor board plug out for drainage. I've had the car in two different dealerships over the issue (it's leaking around the firewall/AC unit) and have spent a few hundred bucks on it....to get no results. It seems worse when the car is parked on an incline with the trunk lower than the hood. So I sometimes back in to my parking space and this seems to do more good than anything. Good luck with your nice ride! Replies to this message: gobig (Jul 20, 2006 6:42 pm)

Replying to: captainkirk1 (Jul 18, 2006 7:07 am) Thanks for the info! One other thing I recently noticed is on the passenger side of the car I hear something "flapping" in time with the rotation of the wheels. If I drive slower the flapping goes slow. As I speed up the flapping speeds up. I didn't notice anything sticking to the tires or protruding out from the side. I realize this might sound stupid. Anyone else ever have this?
#38 of 102 My 1995 Grand Marquois by thatdamncar Dec 08, 2006 (4:33 pm)
I too have the "shudder", "jolt", "hippity-hoppity", 'shake you half to pieces thing' in my wonderful beast. I really shouldn't complain as the car was given to me as a wedding gift and other than the shake down thing, she works great. The RWD thing takes a bit of getting used to as my last car was a '90 Pontiac Bonneville.   I have just discussed that last suggestions of tranny and torque converter flushing with my husband and we will definately try this as we have no record of this being done.

Replying to: euphonium (Jun 23, 2006 9:32 am) My '94 GM (now with 205k miles)had tranny shudder at about 2 years old and 34,000 miles. An independent transmission place told me to put Chrysler trans fluid in it because it contains some kind of additive to reduce friction, which the Ford fluid did not. Never had the problem again.
#40 of 102 Fuel Line on 1993 Grand Marquis by srd277 Jan 02, 2007 (7:34 pm)
My father was attempting to replace the fuel pump. During this process, the fuel lines on the fuel pump broke off in the quick connectors. Fuel lines all the way to the engine compartment are very rusty. He is wondering if anyone has any suggestions on the best way to go about replacing the entire fuel lines.
#41 of 102 Engine misfire, temp gauge flicker, traction light on by horswill Jan 03, 2007 (10:13 am)
Great start to the New Year. Last night driving home in my 2000 GM an apparent mis-fire started. Seems to be at any load, but still accelerates reasonably under full throttle. I was thinking plugs, leans etc. Then the temp gauge went to max for a second or so before returning to normal. Did this a couple of times on way home (8 miles). Also, the traction control light came on and stayed on.   This morning, the 'check engine' light came on.   Any suggestions? Replies to this message: horswill (Jan 05, 2007 10:00 am)

Replying to: horswill (Jan 03, 2007 10:13 am) FIXED IT!   Don't know what caused the Temp Gauge flick, or TC light to come on, but I went to Murrays, borrowed their OBD 2 diagnostic gear, said No 8 misfire. Changed No.8 coil. now fine!   Glad that was cheap and easy ($63 inc tax). I also treated it to a new set of plugs, as they weren't too great (though color was fine), they are due for replacement at 100,000 miles (car's done 85,000), and they were only $24 including tax.

Glad the fix was simple - as is just about every repair on the Grand Marquis.
#44 of 102 Factory Service Manual by rhill7 Jan 09, 2007 (4:33 am)
We just bought a left over 2006 GM with the handling package. I am accustomed to doing or at least understanding our vehicle maintenance. What is a source for the Factory Service Manual?   Thanks in Advance.
#45 of 102 1998/99 Mercury GS Stiff Steering by amcardriver Jan 15, 2007 (1:53 pm)
Only 50k on the clock, regularly check the power steering oil and this weekend checked the pump, but from time to time the steering feel gets a bit stiff. Its soft in straight line but hardens as I turn the wheel left or right and then it eases off as the car runs into turn. The same when straightening up. Can't think what can be wrong saying that the oil and pump seem to be fine.   Tyres are less than 12 months old and wheels have been aligned and balanced. Very annoying feeling but main concern is safety when driving at speed. Any suggestions please?
