No....the rpms differ from engine to engine and from manufacturer to manufacturer. RPM's are always higher at higher speeds.

SOURCE: 2005 Nissan Altima makes rattling/vibration noise

It is possible that you have some timing chain noise, especially if you have the 3.5L engine. The secondary timing chain tensioners on the 3.5 have a known problem, Nissan has issued a service bulletin regarding this and there is an updated part to replace them. It is not a cheap job, but your dealer may give you some "goodwill" depending on your mileage. If you have the 2.5L the problem may a couple of other things...even more serious! They had catalytic converters that came apart and got ingested into the engine, eventually destroying it. Try googling "Altima rattle" and include your engine size in the search. There is a ton of info on the net about noises in these cars.

My 94 nissan sentra doesn't run smooth over 3000 rpm or if you mash the gas pedal


I have a 2000 Chevy Tahoe that did the same thing. I changed the oil pump, new oil, and head gasket. It now has power and doesn't fall on its face when I step into the throttle hard. Hope this helps.

1996 nissan altima will not rev over 3000 rpm


Have you checked Fuel Pressure with a gauge?

Is the Exhaust Converter on there for 17 years & blocked?

Gas Filter clogged?

Does it have a timing belt that could have jumped some teeth?

If you have injectors for each cylinder,have you mailed them
off to be utrasonic cleaned?

I have a 2001 nissan altima and sometimes my car wont go over 60mph would that b gas filter issue or mass air flow sensor


If the gas filter is due, I would replace it as a matter of course. The mass air flow sensor is a possibility...try leaving the mass air flow sensor wire harness unplugged to see if the car runs better. If it does, probably it is bad. However, I would also check the exhaust for a restriction (eg. cat converter could be plugging up), one way to check that is to hook a vacuum gauge to the engine to see if you get normal values. (vacuum should hold steady @ about 20 Hg with engine at 2500-3000 RPM, with no fluttering or drop-off). Also, ensure that all your vacuum hoses are good, and that there are no vacuum leaks (leaks will make a hissing noise).

Stick shift # Automatic RPM


That is normal,If you do the same speed in 4th gear the rpm's will almost double.

The rpm's will repond faster in a manual than an automatic.

In a manual the engine supplies the power required directly to the gear that you have selected thus the engine rpm's will increase or decrease as needed.

About RPM


The RPM's should go up with speed and then level out once you mantain a speed.
