While driving down highway at about 70-80kms an hr it drives fine but when take foot off gas and start slowing down lights start flickering brighter and dimmer then eventually stalls out??...took battery posts off to check alternator then lights went completly out and radiator fan stayed running.....help!!!
Sounds to me like an alternator problem. Did the engine stay running with battery disconnected? Even if it did, the alternator may be too weak. It should keep the lights bright, all systems running, and be charging the battery all at the same time. Have the alternator tested.
It sounds like an alternator, yet you say the fan still worked after you disconnected the battery? And the car was still running? Or the car died out. Sorry, need some more details on this one.

Just trowing some suggestions out there, but, I would check the idle air control valve (solenoid) or the throttle position sensor. If they check out then my last guess would be the map sensor or the vaccuum to the map sensor. Hope I was able to help. Best wishes.

There is a fan relay in the fuse box in the engine compartment. Usually that is the reason why it won't turn off. It fuses in the on position. If you have the manual it will say which one is the fan relay. just pull it out and get a new one. They are not expensive.
Hope this helps

If you notice the car running rich(black smoke out of the exhaust) you might look at the MAP sensor. It is a common problem with these cars,and about 50 bucks at your local parts store. You will find it on the passenger side inner fender just in front of the strut tower, it is a small black box with one vaccum line and one elec. plug. try pulling off the vac. line and plugging it with a bolt the car should idle like that, if it does, you have found your problem. Hope this helps
