I love this car. I have a 1999 Cougar, and I have had it for 3 years now. I take care of it, and that is all you people need to do to be happy with it. Yes, the car takes some work, but be nice to it and it will be nice to you.
- 3.0 V6 turbo Cougar.
I have a 99 Cougar... have had it for less than 2 months now! It was running perfectly fine until about 3 weeks ago; the coolant light came on, got that fixed, now the check engine light is on!!! I wish I would have just put my money towards a down payment to a new car, because now I have to fix this car just to get rid of it! The shop says it's my catalytic converters, which means I can't pass smog test until it's fixed! Also I'm in CA, so it's extremely hard to get a converter for this car... I won't ever look twice at a Mercury Cougar when I get rid of this TRASH! Thought I was saving money purchasing a used car, however I just lost money! My advice, if you car is having lights on and off, is get the problem fixed and get rid of the car ASAP! And to the ones who have great Cougars, I guess you're the lucky few...
The engine light can come on for lots of reasons. Disconnecting battery might make you feel better, but you really need to get the OBD2 codes so you can see what's the problem. Sometimes it's as easy as a loose gas cap, but other times, well that's another story! LOL.
O.K. it's a 12 year old car. I have a 13 year old car and had to deal with the CEL. (Review: '98 Mazda Protege "A Lovely Runner"). I had to replace vacuum hoses, unplug vacuum passages, clean the MAF sensor and throttle body, scrape deposits out of the EGR valve, etc to track it down. A "Seafoam" treatment helped too.
The Contour Enthusiast Group and Mad Moles may be good sources of information for you.
I have the same exact problems, but my CE light came on days after I bought it. The guy at the dealership was kind of a jerk about it when I brought it back.
Was your CE code P0426? If so, did you ever fix the problem? I keep getting different diagnoses. Some say it's the catalytic converter, and others say it's the O2 sensors.
