Try changing the 'idle air controller' value/motor. A $60.00 part
You can remove this part and clean it using any fuel injection or intake cleaner. Carbon deposits sometime build up in the plastic gear and spring and does not allow it to work correctly.cleaning it can sometimes solve your problems.
wires, connecters, terminals
it could be something wrong with the ignition switch, and or alarm
There is something serious wrong, take it back!
I have a 2001 Mercury Cougar it goes in reverse and first and second but it wont go in drive when i put it in drive the rpm just go up.
a slipping transmission, a bad tourqe converter, wrong firing order, wrong gap on the plugs, dist. cap put on wrong, to name a few.
It is quite possible in a 1996 Mercury Cougar, that when the dashboard instruments all quit at once, there is a fuse that has been blown. Most of the gauges in the dash run off the same fuse in most vehicles.
You didn't explain much of what was wrong, but with my cougar I thought it was the latch, but it was actually having to replace the bushings in the door hinge. It used to be that you could just by the bushings kit, but now you have to by the whole set up.
I have a 1994 Mercury Cougar that runs good but burns alot of fuel and after the engine starts the and gets some heat, oil pressure gauge indicates low when there is nothing wrong. I have the same problem with a 1991 Mercury Cougar 3.8, doesn't burn fuel that much but a mechanician told me that it might be a miscontact on the gauge indicator, some dirt in oil pan blocking oil pump or the oil pump is going off. First thing to do is changing oil and filter replacing it by syntec oil in it so it will stay in engine more time when heating. If after that nothing changed check oil pressure at a local garage.
It is leaking. Have a complete fluid and filter change. Replace the pan gasket.
bad fuse, relay, wiring, or motor... get a test light and start trieng stuff
I would like to know if there's something serious wrong with my car
