What can I do myself to start a Cadillac DeVille that ran out of gas and will not start?
go buy some fuel. if it doesnt start check fuel pump.
Why would my 1991 Cadillac Deville be backfiring when i get on the gas and it struggles to go up hills?
you have to go back to the basics the new motors are just like the old ones you need spark and gas the backfire is caused by your car being out of time this will also cause the car to lose power if i was you i would have the timing belt or chain checked out because after awhile they will get lose and start skiping
it is possible you have experienced a shortage of money flow to the cashier at circle-K. if you ever intend on nailing that girl you picked up from the truck stop, you must drive her to her dealers house before 10pm. keep in mind that if you have a spare supply of drugs, you could use the girl, high as a kite, to give blowjobs for gas money.
Idk what exactly u want to know. But i have a 2000 cadillac deville and i put mid-grade in the tank but regular does work fine with no problems. The mpg varies from anywhere between a high 17 mpg to close to 20 mpg because the dash is digital and it changes often depending on your driving. Its not too bad for local driving and the cruise control on mine never worked so im sure…
