I'm confused

they both went out gas went out first slowly now both are out.. it started when i turned on my lights they would go out and nothing worked. now they are out for good... plz help.. thx..

The engine drives smooth, the temp ranges between 204-225. The gas was empty from the dealer, so I gased up 5L and by the time it covered like 10 miles,the gas meter signals empty. Is this normal consumption or terribly odd? What can I do please.

If I press on the brake hard it will idle down. When I am driving if I let off the gass it will maintain speed, without the cruise control on. I just had a tune up done and it has been doing sinse then. What could thye problem be?

when i turn the heater off or the car off the fan is still runing

Car runs fine with just a small hint of maybe a skip. Checked radiator and overflow and found what seems to be oil in both. Car seemed to be burning lots of fuel during usage. Thought of head gasket but exhaust seems to be o.k. NO SMOKE.
Any suggestions??? 1990 Sedan DeVille

It sounds like it's cycling on and off.

How much dirty fluid would be left with a drain, compared to flush?

I know nothing about cadillacs. My dad left his car to me. Looks great on the outside and runs great except that the power locks dont work (you have to do it manually), only some of the windows work, the driver seat doesnt work and the cassette player doenst work. Where can I get this fixed in Oakland CA or in bay area? I am nervous to have electrical done by someone that will mess up my car.

...when turn AC off the light turns off....its a 87 cadillac deville...

looked in radiator do not see water flowing....

front passenger side sounds like its rubbing and squeaking wen u hit bump in road also there seems to be oil leaking from the bottom of the car also some up it is making it way to the top i also see oil of the bottom and side walls of car
