Can a car lose acceleration?

[dpk777]

Seems like my parent's 2001 Maxima (with 50k on it) has lost acceleration?...just doesn't seem the same when I drove it a couple months ago...doesn't have the pickup it used to have.

Could it need maintenance of some sort or maybe they've been using a low octane?


And the engine doesn't make the nice purring sound anymore...it's more like a low rumbling.

Maybe I'm just wrong?

bad plugs
bad gas
dirty air filter

There's a wide variety of problems that can cause a motor to lose power.

Over time your engine will wear and you won't get as much compression.

i noticed this with my last truck. I'd gues I lost 10% of hte HP by the time I sold it 90K miles later.

Beat on your engine, loose HP faster.

Release the E brake. It'll be like a whole new car!

yeah older teh car the lower the power i see.. its true.

I used to be able to make it up the gravevine in 5th earlier pulling at 65mph (last winter), this winter i was pulling 65 in 4th. Difference about 40000 miles.
