1996 Mercury Villager with idle problems

I have a 1996 Villager, with 86,000 and it has developed a severe idle problem. You have to keep the gas to it until it warms up and then it improves enough so you don't have to hold the gas pedal when stopped at a light. I took it to a mechanic, who charged me $80 for a diagnostic check and told me he couldn't tell me what the problem was. Now the merc dealer wants to charge me $150 to run the same test. But they said they guarantee they would find the problem. I'm getting really sick of all these rip-me-off mechanics. Does anyone know any good websites where I can try to troubleshoot this myself. I've changed out the fuel filter, air filter, plugs and wires with no improvement. I change gas, ran some good fuel injector cleaner through it also. Any help would be appreciated. Thanks, Peter Did you ever have any luck. My 99 Villager has problems running rough at idle and driving AFTER it warms up. We have fought with this for a while now and have also replaced the plugs, wires, dist cap and added fuel injector cleaner. I just can't seem to isolate it. The only codes we have been able to pull is for a miss on Cylinder 4 and knock sensor. Most of the things I have read is the knock sensor is probably caused by the misfire of 4. I am just curious if the knock sensor fixed it for you/ Thanks.

The knock sensor is never bad and it costs @ $500 to change. Have to remove top half of engine. I suspect you need to clean the optical cam sensor under the distributor cap or change the oxygen sensor. Here is a site where we help each other with Villager Qust problems.

Particularly with the 99-up 3.0L (Quest/Villager van), the upper bearing in the distributor goes bad at 125K to 150k miles. This will cause the computer to show a number of different false error codes. Simply removing the parts inside the distributor will expose this bearing and any failure will be obvious. This is an industry standard metric "6000" sealed bearing. Get a good Japanese deep-groove replacement. It takes about 20 to 30 minutes to replace this bearing. The bearing can be had from any industrial bearing supply house, and will cost 8 to 20 dollars or so. A spring at the bottom end of the shaft is applying a force on these bearings that they are not designed for. A GOOD quality deep-groove bearing can withstand a bit of such forces. Be sure to clean the distributor out well, and take extra care with the cam position sensor parts, cleaning that very well also to get debris off the optics. I've seen this issue cost owners thousands for false parts replacements, and the real problem is never fixed.

I have ran in to the same problem with this vehicle. I am a mechanic at a local garage in Va. The problem sounds like the distributor. I had a villager that would not idle and would die when you stopped at a red light if you didnt put your foot on the gas. The distributor bearing goes out on this particular model. You can take the cover off of the distributor and see metal shving inside. Hope that helps you.

Well I see this was written a year ago, so I'm probably of no help. However, I had the same problem and it was the injectors. Same code (misfire and knock sensor). I was quoted about 400 labor and 100 for each injector, which they recommend changing all 6 while they are already in there. So, around 1000 bucks.

Van is worth just over 2 grand so I decided to just keep driving it until it pukes .. that was 4 months ago and it's still going.

Hope this helps.

1996 mercury villager as it warms about 3 miles you come to a stop it will still idle but when

Check your air inlet hose(large black rubber hose from air filter to engine)for any cracks, especially between ribs. When there are cracks,when you accelerate it flexes open and creates a giant vacuum leak causing your van to die. Other things to check would be coolant temp sensor,not switch, and have the vehicle scanned if possible.

96 Mercury Villager gas leak from front drviers side

A somewhat common problem on Nissan cars and imports that use clamps for fuel lines. Altho not usually that major.
Often times the rubber fuel hoses leak in very cold weather. The fuel lines going to the tank are on the driver side. So is the fuel filter.
I have to tighten up a clamp every winter on my 98 Villager when the temp drops below 30 degrees.
If the leak is major enough to leave a puddle on the ground you should have no problem finding it.

1996 Mercury villager 96,000 miles- dies out

Here is the common cause of surges, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

1996 Mercury Villager with idle problems

does your villager have check engine light on? If you do I suggest to buy a "Actron Scanner" you can get that cheap online. If you have the OBD code you can research more detail.
My 98 villager usually stops running when it was very cold. After I changed sparks plugs and radiator flush it doing better. How is the temperature meeter? If it is very low always, change the thermostat.
