What happens when you go over 4000 rpm?
The engine computer has a built in rev limiter built in to the programming that will not let the engine go above 3800 to 4000 rpms when the transmission is not in gear and driving down the street. This is a normal protection so you do not over rev the engine and damage it. Was this answer helpful? Thank you for your feedback! Sorry about that.
When to shift to the next gear on the RPM gauge?

Why does my car shake at a constant speed?
Sometimes the problem does not lie within the brakes or wheels; the engine causes it. If your car begins to shake while driving at a constant speed or jerking occurs during acceleration, the chances are that the problem is with the engine and not the suspension. This can happens due to a wrong air-fuel mixture in the engine, which causes misfires.

The 4.2 has plenty of power to stay locked at 50 – 60 mph, even with the car full of family & stuff and even on slight inclines. Actually, on a few occasions I was amazed by how much “suffocating” the engine took before the computer decided it cannot go locked anymore.
Why is my car revving at high RPMs?
But, to answer your question… No, a clogged fuel filter would not explain an engine that is revving at high RPMs without the car moving at an appropriate speed. The most likely explanation would be a failing transmission if it is of the automatic variety, or a slipping clutch if it has a manual transmission.
Is it normal to have 400 ish RPMs?

Why does my snowmobile engine not Rev at 4000 rpm?
Sounds like your primary is engaging too soon, causing the engine to bog and power out. Either jack the back end up off the ground or take the belt off and see if the engine will rev freely or if it still won’t rev over 4000 RPM. This will tell you if it’s an engine power issue or possibly a drive train issue.
What causes car RPMs to go up but not down?
There might be a leaking vacuum hose in the car, hoses deliver air and fuel to the combustion chamber. If it is leaking, the air will mix with the gas causing the RPMs to go higher than it should be. Another thing to look out for is a clogged air filter if the air is having difficulties entering the combustion chamber.
