Sounds like itr is not getting enough fuel. Try or check the fuel filter for dirt or water, and also check the fuel pump pressure to see if it meet factory specs.
Good Luck Jerry

Does the RPM seem to bog down around 3000 - 3500? If so you have fuel delivery problem> Start with the filter.

Hi!

It seems to be clutch problem.

There is a way to slightly adjust the idle,on the front of the throttle body where the intake boot is bolted on,abovt the boot and slightly to the left you will see a hole about 1/2 inch wide and it is plugged with grey epoxy like material. Using a flat head screw driver scrape the epoxy out of the hole and there is a flathead adjustment screw. You can adjust the idle up and down just a few hundred rpm. Hope this helps and let me know if there is any more direction you need.
Please rate this solution.

Thanks
Rylee

SOURCE: The RPM of Nissan Altima stays high when drive over 65 MPH.

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

SOURCE: RPM issue when accelerating

Is this an automatic transmission or a manual shift?
If manual shift,you have a clutch slipping problem.
If automatic,you still have a slipping problem.

Hello. It seems you have an intermittent vacuum leak at high engine rpm's.

1998 lexus gs300 runs at 2800 rpm at 65 mph


At a steady 65 mph, the torque converter clutch (TCC) is engaged. When you accelerate, the ECU disengages the TCC to gain extra torque for acceleration and then re-engages TCC when speed is steady. Its kind of like having an extra gear.

High rpm at highway speed


No idea why you would drive that fast,
but 2800 is about right at that speed

Did you just get the car & never own one that
went to 2800 at that speed

Tap the brake around 55 & see if the rpm goes up,
indicating that torque converter lock-up is working

Don't do that at 70 mph

Hi. I have an '82 F-150 with a 351 c.i. engine, the extended cab version with the full-length bed, 4WD, with only 20,000 miles on it. When I'm driving about 70 mph, the tachometer reads 3000 rpm, which...


Hi

It does look like you have a 3 speed C6, if the PRND21 description is correct. If you do have overdrive, the "D" will be printed in a white oval.

Sounds like it is OK. My Mustang has a 351C with a C6 trans, and 3000 rpm is about right at 70mph.

The defining factor on the rpm will be the Differential gears, which in a truck, might very well be taller gears instead of highway gears, as the taller gears provide more power output at the axles than the highway gears do.

Example:
if you had 3.0 to 1 gears (Highway), that means that the driveshaft will turn 3 times for every complete revolution of the rear wheels(Axle)

If you had 4.0 to 1 gears, then the driveshaft would turn 4 times for every revolution if the axle. Lots of torque for pulling stumps, but on the highway. the engine will have to turn more rpm's to maintain 70 mph vs a 3 to 1.

with the 3 to 1, you will turn less rpm's on the highway, but will have less available low speed power (Torque) at the wheels.

Sounds like the truck is doing fine.

Shifting/RPM problems


check tranny fluid. if tranny fluid checks good then buy a bottle of "lucas transmission additive". this is the best on market. you can buy at atuozone, oreillys or napa. the transmission fluid can only be checked while engine is warm and running in park. another stupid question. when you back up does the car make a funny squeaking nosie? if so then your u-joints are the culprit.

I have 2006 scion xb and when driving the rpm stays around3500-4000 when running 65 mph can it be modified to run lower rpm


3500 is about normal for an xb at 65 mph. My previous ride was a pickup and rolled at about 2000-2500 on the highway. But the XB's engine is way more "tightly wound". Your rpm gage should run at about half of of your speed...ie: 70 mph will be about 35 (3500) rpm, 80 mph will be about 40 (4000) rpm. Freaked me out when I first got the thing, but after researching it Ive found out that with a stock engine it actually runs more efficient at the higher RPM's. The 06 boxes won't redline until 6000 rpm, so unless you are driving 120 on a frequent basis you're good. You can probably have it modified to run lower, but you will lose the awesome gas mileage and overall it is not going to improve the way it runs, and would have no benefit............

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.
