1987 chev celebrity. 150,000 miles. V-6. Auto trans. Car starts right up and idles smoothly. No hesitation, surge, backfire or dying. Severe lack of power under acceleration. Plugs recently replaced. Plug wires as well. Air cleaner too. Also recent fuel pump. Whirring sound from engine as if it is working too hard. When revved high in neutral, sounds like it is sucking air. Revs high then shifts late, when driving. Oil and transmisision fluids look to be normal. No engine smoke. No detected fluid or exhaust leaks found. Car drives just fine except when you try to accelerate, then it bogs down and very slowly reaches speed. Struggles to reach freeway speed, but after doing so, runs wiith no problem. No other unusual noise from under the hood.
