1999 Mercury Grand Marquis

Showing 4 out of 5 Posts | Show 1 Hidden Posts
Question From Guest on 1999 Mercury Grand Marquis

1999 Mercury Grand Marquis engine is not running properly. Idles and revs fine when not in gear. Hesitates and a little rough idle when in gear. Seems to run slightly worse while AC unit is on. What is the problem? Is this a likely O2 sensor problem, or perhaps a transmission sensor? Any help would be appreciated. Thanks!

Response From way2old

What is the mileage? When was the last tune up? When was the fuel filter last changed? We need all the maintenance information you can give us so we will not be asking things that you have already done. Let us know.

Response From Guest Top Rated Answer

Mileage = 100495; as to the rest - car was bought used from son of deceased owner. Son was not sure of any maintenance records. Oil has been changed recently. Car is clean and ran great initially. Only recently did this problem develope. Any info and/or advice you can give will be appreciated.

Response From way2old

I would start with spark plugs and fuel filter. These are rather inexpensive and easily done yourself. You will need a tool to releadse the lock on trhe fuel filter, but other than that, general tools will finish the rest. Ratchet, short extension, a good 5/8 inch spark plug socket and a 7mm or 1/4 inch socket to remove the coils.

Response From Guest

Thanks for the info and the help. We'll give it a try. Thanks again. It is appreciated.

97' Mercury Tracer - Dies after starting

Showing 4 out of 4 Posts
Question From scottcfr on 97' Mercury Tracer - Dies after starting

When I start my car, if I don't put it in gear and drive it immediately it will die. I think it could be the o2 sensor, or the catalytic converter. But, I'm no mechanic.

Response From Tom Greenleaf Top Rated Answer

Can you get codes read which would help. Guessing and tossing parts will just get expensive and a waste,

T

Response From Discretesignals

Ask your friends and family where they take their vehicles to get worked on. Word of mouth is the best form of advertisement.

Response From scottcfr

Where would I get that done? Just any mechanic shop?

2003 Mercury Mountaineer will not start/ no communication/ fuse #41 continues to blow

Showing 2 out of 3 Posts | Show 1 Hidden Posts
Question From dylan86 on 2003 Mercury Mountaineer will not start/ no communication/ fuse #41 continues to blow

I got a 2003 Mercury Mountaineer V8 4.6 that will not start or turn over. Key turns but vehicle will not start. The starter has been replaced and the battery has tested good. There is also no communication when connected to the obdII connector. I also have found out the #41 fuse continues to blow. I will replace it and it will blow when the key is turned to the start position. This is the fuse that controls the HEGO, VMV, CMS and PTEC. I have found the abbreviated acronyms Ford uses but have misplaced them. I believe this fuse controls the PCM, the 02 sensors, the evap sensors and something else. Don't quote me on that as I don't know for sure. I have looked at the wiring and everything looks okay so far. A common issue is the 02 sensors shorting out on the exhaust but that doesn't seem to be the issue. Any help would be greatly appreciated.

Response From kev2 Top Rated Answer

1st suspect is always anything not from ford/mercury aftermarket add on etc.
Fuse 41 battery fuse box is a 15amp.
heater circuit all 4 o2 sensors..
Vent valve... part of EVAP
EVR, vac reg valve... part of EGR
Vapor management, part of EVAP
PCM power relay
were there any codes or issues before the fuse blowing?
I would start with o2 sensors..

Response From dylan86

Hey Kev. Thanks for the assistance. Everything you mentioned has been checked outside of the EVAP system which I plan on looking at today. There were no codes I am aware of before the fuse blowing. The check engine light was not on either. Now, there is no communication when connected to the obdII port with a scan tool. As far as I know, the car was running well with no symptoms prior to my dad stopping somewhere briefly. His car was in the shade during this time and when he came out there was nothing. I will keep you posted.

2005 Mercury Monterey

Showing 4 out of 6 Posts | Show 2 Hidden Posts
Question From chewy426 on 2005 Mercury Monterey

Hi Folks,
I have a 2005 mercury Monterey van with a check engine light on. Autozone diagnosed either a mass air flow sensor or O2 sensor problem. I tried cleaning the air flow sensor with air flow sensor cleaner but check engine light is still on. Any suggestions on which part is more likely to be at fault?
The van runs and drives great otherwise but need to pass emissions. Thanks in advance for any input


Links from other site removed.

Response From Hammer Time

First of all, understand this. the employees at Autozone are wanna be mechanics that couldn't diagnose a cat with the runs.

What you need to post here is the exact code numbers being stored and professional will advise you.

Response From chewy426 Top Rated Answer

Hi,
thanks for the reply, the codes are P0171 and P0174

Response From Hammer Time

OK, that indicates a lean condition that the computer has reached it's adaptive limits and can no longer compensate for it.

I have seen these codes often on a Ford and it is nearly always caused by a severe vacuum leak, usually associated with the PCV line or one of the rubber connectors that feed vacuum to other components. They can sometimes be hard to spot because when the engine is running the suction pulls a hole open and then the hole closes when the engine is shut off. With the engine idling, listen very closely for hissing noises and try to follow them to their origin.

Response From chewy426

I will give it a try....thank you!!!!

Response From Discretesignals

They also like to leak between the upper and lower intake when cold. You may need to have it smoke checked to find the leak.
