Engines - Mercury - Cougar :: 1999 - Suddenly Lost Power When Driving Down The Road
Feb 11, 2014
Description of Problem: 1999 mercury cougar 2.5L V6 automatic trans: I was driving down the road and suddenly lost power. The engine was still running but sounded a little rough so i turned it off. then it wouldn't start. After having it parked for a couple months i started looking ant it and notice that the starter is spinning the flexplate but the harmonic balance isn't turning. It does turn by hand with a socket. After talking to a mechanic i was told a used motor would run. He said i broke the crank or timing chain? I thought if it was the timing chain the harmonic balancer would still turn, he didn't agree. and i thought it was unlikely that the crank would just break driving down the road. What it could be? or how i can narrow it down. If the flexplate or bolts broke off would that cause my problem?

93 Mercury Cougar 3.8L V6 with just over 83,000 miles
l've been trying to figure out this issue for ages, but can't seem to find the root of the issue. When driving and accelerating to 40mph, the rpms drop and GET STUCK at exactly 1000rpm. Forcing the accelerator down makes the engine bog and sputter and not go any faster. No check engine lights whatsoever.
The idle is very rough and low in park (700rpm compared to the regular 900) and very low in drive (500 compared to 650-750). When stopped in traffic for a while, it begins to shudder and shake like it wants to stall right there. Now let me run down the extensive list of parts l've thrown at it, bringing only temporary results:
Replaced catalytic converter
Replaced IAC valve
Replaced O2 sensors
Rebuilt transmission (runs great, so l've ruled that out)
Replaced 1fuel injector
Replaced MAF sensor
Replaced motor mounts
Cleaned throttle body extensively
I asked a guy at a Firestone and he said that l needed a valve job. Asked another guy at another place, he said l needed a fuel system cleaning. Asked another guy under a tree, said l needed a new speed sensor. What could be the root issue? l was thinking carbon build up over 22 years maybe? Almost all 83k of those miles have been city miles...
This car is my baby, all l want is for it to be able to handle highway speeds without a hiccup. l'm keeping it and plan to see 100k hit the odometer and many more miles!

I'm not sure whats wrong here but i think its a plugged exhaust or clogged catalytic converter but whats happening is when I drive my car is lacking power huge, sometimes ill push on the gas and it will hardly move and start chugging but if i push down more it will go. When i go on on ramps to the highway as soon as i hit 70km it starts to chug then i have to push the pedal to the floor to get going,then after a while the car will start to shake after 5-10 minutes of driving and i have to let it cool down or it will keep shaking or just go back onto city roads and it doesnt shake as bad. Once im off the highway my car will begin to shake more at 20km and 60km i have no clue why!

I have a 2001 Mercury Sable with 114k miles. Just bought it and it ran fine for the most part until one day while coming home from work. It was still running but lost a lot of power and wouldn't go fast at all. I took it to my mechanic and he told me that this car has 3 converters on the exhaust system. First of all, I think having 3 is overkill and secondly, I am wondering why these things are so expensive. The one up front that mounts to my manifold is $350 just for the part. The one in the back can be bypassed (legally) but why did they make this system so complex and what are my options at this point? If I found a Sable that was being parted out, could I use the converters from that? Would it have to be the same year?

I don't know what is wrong with my truck. I don't know what this symptoms called, but It felt like it was missing a beat. The engine suddenly lost power for a second or two wile driving. It did this few times. Is it the engine or the transmission? No check engine light is on. 2001 F250 5.4 V8

I've also replaced spark plugs properly gaped fuel filters hell replaced the suspension air filter oil change the works and well were all at a loss of what it is?

My mercury Monteray 2004 model, suddenly loses power while driving. This has happened both on the freeway and on the local roads. I then have some how driven it to the shoulder. After stopping for couple of minutes when I restart the car it works and I have been able to drive it. I have taken it 3 times to the dealer and he has not been able to identify the problem. I am extremely scared of driving the vehicle. We even had flight recorder from the dealer on the vehicle and recorded the incident 3 to 4 times and still the dealer has not been able to figure out what the issue is. They say that they have tried several times and have not been able to recreate the issue. They say that they have tried to recreate the issue with a computer attached so they can record the issue when it occurs. But apparently they have never been able to recreate the issue. Other wise the van is in excellent condition. What could be the issue? We have not been able to use the van for over 6 months and do not know what to do with it.

I have a 1999 mercury cougar and recently my acceleration has gone down huge, when i try to go onto a highway my car starts to chug, i have to push the pedal to the floor for it to actually start picking up speed a little faster, and once in a while i smell a sulfur smell!
Another symptom I have is my engine heat goes up 3/4 of the way when this happens! Also once in a while after driving while its hot the car starts to shake lightly then shakes a lot until i get off the highway and bring my speed from 110km/h to about 60k?

My uncle bought an '05 that stopped running one day. He was driving down the road and engine lost power. He was able to coast into his driveway. Unfortunately, it's been 10 years since I've work on a 6.0 and no longer have any of my computers.
He did state there is no check engine light. He's going to change the filters today / tomorrow. I'm hoping to make it down there this weekend to look at it, but what to look for. Even more unfortunately, we really don't have any specialty tools or gauges.

I had to drive 70 miles last week the temp outside was 98. My air conditioner was blowing cold air, I parked my car for 30 minutes. When I started my car again the air would not work, no blower nothing. I was on my way to have it tested, turned it on and it is working and blowing cold air. I do not to be stuck again traveling and it stop.

While I was driving my car suddenly was losing power.I tried to hit the "gas" pedal harder and it didn't react.It stayed on the same gear and after 2-3 seconds it was ok. After 10 minutes it happened again but this time I couldn't do anything. I thought it was the transmission problem so I went into manual mode to shift it down. It didn't work at all - I was shifting down but didn't have power so I had to stop. I stopped put in P turn engine on and everything came back to normal.It's worth mentioning that one time time I had to pull over and I didn't turn the car off. After couple minutes the car started to vibrate and died. I turned on and everything was ok. Fuel filter or is it something else?

Up until this morning I thought I had almost a perfect car with a potential of lasting for 10 years but this morning, while I was driving on a local road with 35-40mph, so suddenly my car stopped moving and I couldn't even pull over as it completely stopped with no error or any warning/alerts! So, I turned it off and on again, it started working but I was still nervous if it would happen to me again while driving on a freeway but it didn't and I have made to work safely.
Now a question is should I bring it to the dealer today and have them run their diagnostics on their computer to see if anything is wrong with the car engine/ battery/ or anything else or should I just reboot it like we do for computers and go on everytime it happens? It's just little scary to think of its happening during a busy highway driving! I have driven it since July and has about 14K and I have had a good MPG of anywhere between 50 to 60.

While driving a mountain road (hwy 17) going downhill this morning I lost power braking and power steering and a got the following error message on the display
TRANSMISSION P LOCK MECHANISM
PARK CAR ON FLAT SURFACE AND APPLY BRAKES
I was able to stop the car on a flat area. I turned the ignition off and then restarted the car and the power steering and brakes came back, but the red triangle remained. I drove to the Toyota dealership and left the car for service.

Driving down the road, vehicle lost all electrical power and died. There doesn't appear to be any juice at all to start it. The battery is fine (along with the terminals), the starter is okay too (although I don't see why that would affect total electrical flow). There were not any alarms on the vehicle. Is it the fuse box (negative terminal) or possibly the alternator? The alternator had been charging, and the battery showed that it had juice left in it. What would cause the vehicle to just die like that, in the middle of driving it? It's an LS type blazer with a 4.3 L engine.

2004 F-250. 6.0 I was driving down the road when the engine dies. It was like I had turned off the key. When I tried to restart it, it was no click, no starter sound, nothing. The glow plug light remained on, even while turning the key over. What could cause this?

Comming back from hunting today my truck suddenly lost power and stepping on the accelearator had no effect at all. We were on the highway thru the mountains but on a fairly level stretch for a few miles. Managed to pull the truck and toy hauler over and the engine was running fine but stepping on the accelerator had no effect. The check engine light came on every time I stepped on the throttle and went out when I released it. It started fine but no throttle response. Switched around a bunch of relays and checked the fuses and still nothing.
Not liking my parking spot i tried to see if it would move down the road at an idle but it would not. Then I thought to try it in 4 wheel low and as the shoulders were soft it wouldn't move forward so tried reverse and went back a foot, forward again and moved a foot and a half. did this several times and all of a sudden the throttle responded, took it out of 4 wheel and it ran fine all the way home. What would have caused this? I was ready to call a tow truck which would have been several hundred dollar bills for where we were and with the trailer

Ok after rebuilding trans and being down a couple of weeks, I went on my 1st run since completing. Noticed when I started truck this morning it didn't turn over as fast as it was. 30 miles down the road Airbag Light comes on, and then volt meter dropped to 8 volts. Got stopped with truck still idling checked everything I had the tools to do so for. Decided to get back to my shop where I had tools, and 5 more miles and 55 mph truck just shuts off. Lost all power, truck would only click. Put my booster box on battery and gauges went back to normal but still wouldn't turn over but maybe once? Only place within a mile of my location was Walmart. Bought 2 new group 65 batteries, installed them and Shazam cranked right up no more problems. Short of the story bad batteries that checked Good with a load tester don't mean squat!

Is it possible for the roof of a 1996 Mercury Cougar to buckle or crease from a rear end accident that has caused frame damage but no damage to the quarter panels? Bumper looks fine but a frame is off on Mash and Sway.

I have a 2002 Mercury Cougar and ever since i bought it (8 months ago) it is fueling up really slow. It takes about 20 mins to put 13 gallons of gas in. I have to just barely squeeze the handle to keep from the gas spurting back out. Its so slow that you can count the cents as it adds up. If i don't hold it really slow the gas comes spewing back out the neck of the gas tank, or just bubbles back out and shuts the pump off.
I thought it could be that my evap canister was plugged or the lines running from the gas tank to it, so i brought it in and they blew out all the lines with an air compressor and they said it was all clear. Its getting really frustrating standing out there at the pump for 20 mins. I really want to get this fixed before the COLD of MN winters comes!!!
