1986 Sedan DeVille Fleetwood - uphill sputter and losing power
What is your question?
I have a 1986 Sedan DeVille Fleetwood that has just started to sputter and lose some power when going uphill. This seems to happen more when I don't have a good 'running start' on the hill, like coming from a stop light at the bottom of a hill. The car runs great otherwise. Have googled and found a similar situation where the solution was mentioned that it was a fuel pump. I want to confirm that potential diagnosis before taking it to a mechanic. Thank you!

Its hard to guess without being able to drive the car and experience the problem first hand. Loss of fuel pressure or delivery is a likely cause which could be due to a restricted fuel filter or failing fuel pump. The problem could be a slipping transmission or restricted exhaust but the mechanic will first drive your car and based on the test drive will have a feeling which way to go diagnostic wise to figure out what to do to repair your car.
