'87 omni fan staying on

[lakotie]

hello all! i recently travelled 3500 kms in my 'lil omni, out to calgary from ontario, i must admit, one of the nicest cars on the highway, anyways, 2 weeks AFTER i got here, we had 3 days of rain, during the first day of the rain, my car started to idle low, i lost a lot of power,decreased fuel mileage, the tach stoppd working and the rad fan wouldn't shut off. plugs look a little on the rich side, vac lines ok, cap/rotor good, carb body tight, fan relay looks good ( i opened it). with the car ign on, as soon as i plug the relay back in, it clicks and the fan comes on. any help is greatly needed, i don't know anyone out here in calgary that can help, other than this board.
thanks guys
chris

Not sure if I can help,I have some wiring for 85 (Same?) Does the vehicle have A/C? Does it have 6 wires at the Fan Relay? Does the vehicle use an After Run Relay?(on R/S Rad Support)

Check for codes. Something is wrong and the car is in "limp" mode. That is why your fan is always on and it is running bad.
I just saw that you said it was carbed. I am not sure if they work the same way.
