  • Sorry - I don't have an answer for you....However, our 2000 Cougar has been doing the same thing that you describe. Our mechanic can't seem to find the problem either! Did you have any luck getting this resolved? I'm curious to find out what is going on.....
    Thanks!

  • I have a 1995 cougar, v8 4.6L. I have replaced the EGR valve twice and the other 2 components that work in tandum with it and I still get the egr error code pop up. I have made sure the exhaust tube is clear of build-up and it makes no difference. Is there a control module that is responsible for the operation of the egr and it's components? Anybody have a fix??
  • This was awhile ago i dont even know if ya'll are still there but i will tell you that some cougars were brought in for a recall on the alternator wiring the Red Jumper wire in the three prong plug needed to be spliced and connected to the "output" on the alternator this helps with the wiring thats running through the engine itself already i did mine like that and its running great :)
  • Mine has been doing it. My cat is old over 250K on her. Been tring to fix this problem for the last 3 months. Will try alternator wiring suggestion and let you all know. I am not ready to retire her yet!

    I am having the same problem recently, I had to get the battery recharged and it held a charge for only a few minutes and when I started to drive it shut off repeatedly and my dash board gauges went out. i had the alternator replaced last year and it seems to me that the alternator is draining the battery down. if this is the same problem you experienced please reply back. If so how much did it cost to fix or was it covered under warranty or recall status? THanks.

    I am a newbie to this site, have a couple of questions. My son has a 2000 Cat, he has been getting the following trouble codes, 0420 and 0430. We cannot find a service manual for this year model car. Are these the codes for the 02 sensors, banks 1 and 2? Where can I get a Haynes or Chiltons manual for this car.

    Thanx,

    installed new coil new command module and new computer box. car isn't getting spark or fuel to injector. fuel pump is working. Also new battery. Car has been sitting for about 6 months. only has 78,000 actual miles also checked all fuses one 5 amp fuse has now power at all. All the rest are fine. Car would start and ran rough then shut down. Let it set for a few min. and restarted. would die out on acceleration Now won't start at all

    I just come back from AutoZone. They not only give you the codes, but now (my local one at least) give a print out with description and probable causes.

    On my 1999 Cougar, the error referring to lean banks (from PCM) are P0171 (bank 1), P0174 (bank 2).

    Also, P1131 indicates that the ECM detected lean limit on bank 1

    1999 Mercury Cougar, V6, Auto:

    We found a disconnected rubber hose (ca. 1/3 in = 8 mm diameter). It has a 90 degree plastic elbow and plastic mounting slot on the loose end. The fixed end ends up in the transmission housing on the top, right under the battery bracket.

    When blowing into the hose, trans fluid comes out of the trans dip stick.

    We already spent hours trying to find where that hose connects.

    Can someone help?

    I have a few pics (will try to upload if possible) of the hose.

    Need urgent answer (intake, battery, carb, etc are currently all off - can't use the car).

    Thanks.

    i have a 67 cougar that wont start,it turns over if you jump the solinoid it has a new ignition switch and a new solinoid but wont turn over with the key.
  • PF_FlyerPF_Flyer Pennsylvania Furnace, PAPosts: 6,058
    Since it turns over when you bypass the solenoid, either the new solenoid is bad or there's something with the wiring to or from the solenoid.

    You might want to post in the general "No Start" Problems discussion over on the Maintenance & Repair board as well

    Hello all, sn5bah here, maybe one of you can help me with this one. My 2000 Mercury Cougar gauge shows that it is overheating, the thermostat has been removed and the whole system flushed. New water pump installed. Water pump belt broke off yesterday. Is this hard to replace, payed a mechanic to replace the water pump, but this time I want to do it myself. Need a quick response, this is my only vehicle.
  • V6?Could be IMRC control unit faulty.This device controls the opening of the valves at approx. 4000rpm to allow max power!

    did you ever get a proper diagnosis for your problem?
    Was it in fact the IMRC???
  • Hello CSG,

    Long time no chat. So it seems recently my gauges started going the full distance from 0 to 160 upon startup. Is this new? Has the cougar always done that? I don't think it has. All of my gauges go the full distance. Does your cougar do this? Is it possible that it has always done this, and I haven't noticed in 7 years?

    That and tonight the cougar didn't start. It just clicks. I'm thinking the battery is low, though the highlights are bright and the internal stereo, lights and etc are fine. I've been warned a couple of times that the battery is low. I think that will be the first thing I change.

    What do you guys think about my gauges.. am I just stupid?
    Thanks!
  • Need help with my cougar. Temp guage shows hot. I have replaced the coolant temp sensor three times Bought two new ones and tried one from a junk yard. One of the new ones did not mark at all on the gauge. The one from the junk yard and the other new one mark hot. I have installed a new water pump, replaced all of the belts, replaced the radiator. Put a new radiator cap, had the whole system pressure tested. All checks out to be good. Pressure holds up, no leaks anywhere. What can I check to fix this problem? Any and all help will be greatly appreciated.

    Have you measured the actual temp of the coolant (to determine if the gauges/sensors are wrong)? An IR temp sensor is useful. Even the temp of the readiator metal or coolant hoses will give a good approximation.

    How soon do the gauges show "hot"? If soon after startup, your coolant thermostat is stuck and won't open. In this case, one of the rubber hoses is hot, while the radiator is still cold.
  • If I am on the highway doing 70 mph, it takes about 10 mins. for the gauge to start marking hot. Have had it checked with an IR temp sensor, have checked the hoses to see if any are collapsed and none are. Water in the bottle, does not boil out. Thermostat is brand new.

    I'd say: if not done already, change the coolant termostat ($6.99 at Autozone), install a lower temp than factory (180 deg F or less). Its not that much work and costs nothing.

    Are your fans kicking in?
  • E-bay our buy it at the dealers.

    I have a 2000 Mercury Cougar and about 2 months ago the check engine light came on – the OBD-II code was P0128 - Coolant Thermostat (Coolant Temperature below Thermostat Regulating Temperature). All seems to be well with the car.

    I live in WI so it is very cold now (Jan/09) and overheating should not be an issue; the car is producing heat in a timely fashion and it isn’t running hot. I disconnected the battery to see if I could get it to kick out the trouble code again. The check engine light went away – but came back about 2 weeks later; I ran through all of the same steps and got the light to go off again.

    On my way to work this morning as I switched the heat from defrost to deforest/floor and the check engine light came on again and as it came on I remembered that this was the same thing that I was doing (switching the heat) when the light came on a few weeks ago.

    Could there possibly be any connection between the heater and the check engine light?
  • im sure u already have this answer, but it doesnt go anywhere, its a vent.
  • vtraudtvtraudt Posts: 52
    I learned back then from the posts that this is going no where, just an open vent hose.
  • The check engine light is it the one on the dash our the one in the head liner?
    If it is the one in the head liner ( the shape of a wrench) it is telling you that it is time for an oil change, there is a spot in owners manual to reset it. If it is the one on the left side of dash is the you need to pull the heater controls out and clean them and see if that takes care of it
  • HELP!!! My baby, an 86 Cougar, has developed a problem and you don't know when it will occur; but seems to happen after getting warmed up. For instance, drove to work, everything fine; on way home stopped by store. Waiting @ red light, engine idle fine...light turns green & I press the gas and she bogs & dies. Started back up OK, but then had to keep foot on brake & gas when slowing or stopping or car would die. I'm not ready to give up on the old girl---she's been too good to me for over 20 yrs. Up until now, she ran when all the others would break down!!

    Thanks,
    86 Cougar
  • Where is outside sensor located on my newer Mercury Cougar that registers the outside air temperature on the inside of my car? Ive always wondered where this is located on a car.
  • My son car will shut off when driving down the road it will do it only sometimes and he can only get heat or air through the defrost vent will not come out the vents in dash. If anyone can help I would be very thankful he is very upset it's his first car thanks for any help :cry
  • vtraudtvtraudt Posts: 52
    We had the same problems:
    - shutoff when driving: it starts with the lights going dimmer, then the instruments go all wacky, then the engine cuts out. Daily recharging of the battery helped to get by for 1 or 2 days. At the end, we changed the alternator, which fixed it in our case
    - no heat/air coming from vents (except defrost): this was going on for more than a year. This week we had to take the engine apart (white smoke, fouled up spark plug: looked like head gasket. It is now back together; we'll see). In the process, we found a small plasctic vaccuum line broken. I patched it up by using a small (just to fit over the plastic line) and a larger (that fits over the first) shrink tube to connect the 2 broken lines. If/when the engine is running again, we will report if that solved the problem (VERY likely).
    Let me know if you need pics to identify the tube which caused the problem in our case (could be any vaccum line though; vents are moved by actuators powered by the engine vaccuum; if you have a leak, the vent stays in its default position, which is "all air to the defrost").

  • We found a line vaccum line off but do not know were it belongs and the diagram under the hood does not help and the book only shows the line for a supercharger and we have a 3.8L with out charger my son never said the dash went crazy it just shut off the started thanks for the help I will keep tring to get it.
