Mercury - Grandmarquis :: Check Engine Light Is Dead
Aug 11, 2012
For years, intermittently, my Check Engine Light was on steady. The Ford dealer tried four times (at a cost to me of nearly $400) but was never able to fix the problem. I was always able to get it smogged because I took it in during those periods when the light was functioning normally. But now I've got to get the car smogged again and the light is dead. Could be the bulb or something else. Should I take it to an electric shop or a regular mechanic? I understand that CEL issues are common to Fords of this vintage, but the Ford dealers haven't been useful.

I have a 2001 Mercury Grand Marquis. The check engine light came on and AutoZone diagnosed it as a misfire on Cyl. #4. I changed all the plugs but I do not know how to turn off the light to see if I fixed the problem. How to turn the light off.

I have a 99 Grand Marquis, I drive all week long in the city (check engine light dose not come on) but soon as I get on the interstate on the weekend the check engine light come on (codes 0171 @ 0174 ) . I also hear engine knock at certain times when the motor is under certain accel. conditions.

The customer brought in her 130,000 mile 2000 Mercury Grand Marquis complaining that the starter would click several times as she turned the key again and again, before it would make the the engine crank like crazy. I saw that the positive battery cable was badly corroded, and replaced the aftermarket end with a new aftermarket end. Everything was nice and clean. No difference. I tested the battery for load voltage with my good old Sun VAT-60. It tested good, sufficient voltage after 15 seconds under a 100 amp load. I removed the fuel pump relay so that the car would not stay running for long, and then would not start when the starter did engage. It drew 120 amps while cranking. That's within spec for a fully warm engine.
I think what she has is a bad solenoid atop the starter, or perhaps a bad spot on the commutator that moves slightly with each click until the brushes are in another position. Then it will turn OK.
I think a new starter is needed. Am I on the right track? I don't want to crawl under it unless I have to, and she doesn't have money for me to make a mistake.

I'm having several problems, and I'm wondering if they are related: Sometimes the heat/ac/vent blows on the windshield instead of where they are supposed to be. Occaisionally it works at first, and then changes after a few minutes to blow onto the windshield.
Sometimes I get a buzzing sound under the hood. Usually when I'm stopped, but sometimes while moving. The car idles high when this happens. If I tap the accelerator, this usually stops the noise and the idle drops to normal.
This morning, the brake warning light kept coming on while using the brake. The fluid level and pedal are OK, and the car stops OK. Then the buzzing sound came on, the engine light came on, and the brake warning light went out at the same time. The brake light hasn't come on since. The scanner tool indicates the IAC was running too fast.

This is for our 2005 Mercury Monterey. The check engine light is on and the code says P0193, Fuel rail pressure sensor circuit high input. Last week we were waiiting in he car with it running on idle and heat running, about 5-10 min, later the the light came on and has remained on, so checked for the code and above code displayed. Possible causes/fixes could be broad as per the sheet printed at ORailey's for this vehicle, but based on above info can it be narrowed down? How urgent the repair is, needed to show right away? What could be done at home before taking it in? car has around 108k on it.

Our 05 mercury monterey is riding rough and the check engine light is blinking all of a sudden. Two days back while driving home it was raining and we accidentally drove through a puddle, did not notice due to night time. After that it suddenly the light started to blink and engine felt rough. Checked the code yesterday morning and it showed cylinder 3 misfiring, no other codes came up. No one was available to check it yesterday and today. Have not started it again. Anything can be done before taking to the mechanic? I believe the number 3 cylinder is at the back side and not accessible easily. What could have happened?

Although it starts most of the time, about two times a week it will act as though it's going to and won't. We had it in a shop for about 3 weeks and the mechanic said it started every time for him. When I got it back, within a few days it would not start. I try after about an hour and it starts. He ran diagnostic tests and nothing showed up. I want to give this car to my teenage granddaughter and I can't have this problem.

Getting slight vibration when traveling at about 60 to 65 mph. Tires are almost new and had them rebalanced about 2000 miles ago. Shocks are less than a year old. Wondering if it is a wheel balance problem or possibly an alignment problem.

How the HVAC system on the big Merc and Crown Vic are controlled. One answer says it's vacuum, another says it's electrical, another says electronic via the BCM. Which is correct? Does it have an electric servo to move the flapper door(s) like the Taurus I'm familiar with? Even the BCM has to have something to tell to move the flapper doors.
In the car I'm looking at, the lines into and out of the evaporator are cold when A/C is selected and the compressor clicks in. That makes me think the issue is with air direction. All I have to do is figure out why.

Have a 2000 grand marquis that will not start after it gets warmed up. Recently had two occasions where after driving for about half hour and it's shut off, it will not start. Cranks good, but will not start. After it "cools down" it will start. Have had it to my mechanic and the dealership. They can't find anything??? They say it has to get worse before they can make it better. They don't want to start throwing parts like fuel pumps at it.

So I went to start the car (2013 C3) and it wouldn't start. The batter was horribly dead (dim screen and would only go into POWER ON mode.) I charged the battery for like a half hour using a plug in charger using the hood terminals. When I tried to turn it on later, The only thing that came on was the check engine light (really dim) so it's not charged up enough yet obviously. The issue is now it won't turn off. That check engine light is still there. No other screens are on and the vehicle doesn't make any other noises (door ajar, etc.)

My garage was struck by lighting this morning, and about two hours later I heard a very loud snap coming out of the vicinity of my garage. The snap was so loud, my ears were ringing. When I went to start my car (2002 Mercury Grand Marquis), it would just crank, but never turn over. The interior lights and trunk lights did not work, so I replaced the battery thinking that the power surge could have affected the electrical system of my car...and I needed a new battery anyway. With the new battery installed, all of the lights once again work, but the car still will not start. The voltage meter is low and it never runs low. I tried resetting the fuel pump shutoff, but it was never tripped and I can hear it pumping when I turn the key on. Is it likely that the mechanical failure is due to forces outside of electricity even though this car has never failed to start, or could the electrical surge have affected something else (alternator, fuses, etc.)?

My windshield wipers do not park all the way down. The left one is up at a 5 degree incline, the right one more like 15 or 20 degrees. I went through a car wash today, and the air dryer blew them all the way to the left, and back to the right a little. I turned them on and back off, and they returned to the original position (5 and 15 degrees). Car is 2002 Grand Marquis LS.

My '03 Grand Marquis "shudders" when I accelerate, especially up hills. It feels like it cuts in and out momentarily, shaking backward and forward. Here is what I have had done, based on mechanics' advice: replace spark plugs, replace fuel filter, clean throttle body, clean mass airflow sensor. It still does it after all this and I am stumped.

Today while driving my 03 marquis the check engine light started blinking, after a few blinks I noticed it stopped . But a few moments later it started blinking again then stopped, so on an so on. I also noticed that the car had a immediate loss of power and it seemed like my car was missing, and while trying to give it gas it would shutter. It never killed on me but I can tell it ain't running right. A friend of mine told me to push the brake down while car was running an in drive, an give it gas like you was going to,"power brake it". I did, and instead of it power braking it just shook forward as if it only had 4cyl instead of 8cyl. then my buddy said its a bad "coil", no how he knows that idk. But is that true or what it might be???

We have a 1994 Grand Marquis. Sometimes when driving the check engine light comes on and suddenly she doesn't want to accelerate very fast at all. If you do try to hit the gas, it sounds like the engine speeds up but there is no change in acceleration. It is also hard to get to/over 50mph. If you pull over and rev the engine a few times (slowly) there is an audible click from somewhere inside the engine. It will happen a few times and then the car seems fine. Inevitably the issue will come back a some miles down the road.It doesn't get driven every day and so far we have not had the light come on when we are near anyone that can read the error. Also, it resets and is not on if you turn the car on and off, even if the problem persists. It only comes on while driving (though it will stay on if put into park and left running). Oh, and possibly related, it seems that the air that is put out form the defroster is very damp when this happens (sometimes).

Several minutes after I start driving in the morning, my car starts making a strange noise under the hood. It sounds like a motor running, or a strange buzz. After a few minutes, the noise stops stops. When it does, and if I'm stopped at a light, my engine jerks one time. The engine actually shut off one day, but I could start it right up. It does this once during the trip. The speed of the car or engine has no effect on the sound, but it stops if I turn the car off. If I restart the car, the noise does not return.

What would make a 2000 mercury grand marquis stall when turning right? I turned the key and it started running again. Check the engine light and it was po442 which is the emissions leak.

So earlier today when I tried to start my car it wouldn't start! I tried cranking her over twice and I got nothing. The battery gage needle didn't move when I tried starting her up the few times. What's weird is that I took my other car (parents) out to run the errands I needed to run and when I got back I thought to myself "well maybe the battery is dead and needs to be jumped" that makes sense right? So as I pull up next to my car I decided to try starting her one last time and when I put the key in and cranked her over she started right up! Not a stutter or anything! So I'm left with the feeling that maybe it could be a failing alternator ? Or possibly a loose cable or something ?
Btw the car is a '98 Mercury Grand Marquis.
