Which did you "unplug"? The Mass Air Sensor or the Idle Bypass Valve?
i posted on here a few days ago with a similar problem . i read what you did and thought i would give it a try but i just un plugged it . car runs better than it ever has . i almost junked it cause ive been trying to figure out this problem for months . thanks for your post
Thanks....I will be working on that today...you are right on the price...but the IAC valve is all the way in the back of the engine behind the throttle body...it looks difficult to even get a tool around there any suggestions?
This sounds as though it might be a bad Idle Air Control Valve, which is not really difficult to change and I believe is in the $60-$80 price range. I had the same problem with my 01 MGM and the IAC was the problem.
I had replaced the MASS AIRFLOW SENSOR a couple of weeks ago because during cold starts I would have to wait a couple of minutes just to warm up the car before the car could move forward, it would basically jerk back and forth and stall before pressing on the gas. Now, that doesn't happpen, after it was replaced no more hesitation, but now I don't hear the engine, no more ... Read More
I currrently have a 1994 Mercury Grand Marquis in am wondering if 22" wheels will fit on the car without a lift kit
I have a 1994 Mercury Grand Marquis and the headlight switch and plug melted around the part that controls the parking and dashlight. It happened once before and I replaced both parts. It happened again just recently but I can't seem to find a short or damaged wire anywhere. If anyone has any idea why this is happening I would appreciated the help.
I too moved from a 1994 to a newer one - a 94 Grand Marquis LS for a 2002 Grand Marquis LSE. The newer one handles better, but the older one had better road isolation. The window regulators were a weak point on the older Grand Marquis - the only weak points on the newer ones is the cost cutting in certain areas by Ford - the bugs have been worked ... Read More
I bought a 1994 Crown Vic Lx new in July 1994 and in April 2006 bought new a Grand Marquis Ls. The safisfying experience with the 94 Vic, brought me back to consider and buying the 06 Grand Marquis. I kept my 94 because it still rides and looks great. My 06 Marquis, I hope will be as good a choice as the Vic has been. Wish they had kept the ... Read More
If by automatic headlights, you mean headlights that automatically turn on when it gets dark, the answer is yes.
I have a question for anyone who has a 1994 Mercury Grand Marquis LS... does that year have automatic headlights? Any help anyone can give me would be most appreciated. Thanks.
I have a 1994 Mercury Grand Marquis with about 119,000 miles on the odometer. I discovered about a week ago when I checked my oil level because the oil light came on that my oil level was quite low. It took three quarts to bring it up to the full line on the dipstick. Yesterday I added about three more quarts. Not being a mechanic myself, I always thought that if ... Read More
Since I am new to this forum, I apologize if my issue has already been addressed over and over again. I have a 1994 Mercury Grand Marquis with about 119,000 miles. Recently I've had a problem with the shifting of the transmission. While I am driving, the transmission will suddenly go out of gear (or into neutral). A few seconds later, especially if I either rev the engine or slow down, ... Read More
