The computer is going to shut fuel to protect the engine thus limiting rpm, if there are no other problems with idle or throttle what its doing apears to be normal.

SOURCE: 2000 pontiac grand am 3.4

Hi Tom,Did you ever figure out what the problem was? My Alero with the same 3.4 motor is doing the exact same thing between 3000-4000 rpm while driving sometimes. Mine won't rev in park over 4000 either, but I think they are all like this.
Thanks,
Mitchell

2.4l has gas in oil and no power


check the fuel pressure regulator and the map sensor vacuum hoses. as for the not revving above 4000 rpm is what the computer limits the engine to with no load on it, like in park or neutral.

I have a 2008 Ford Escape, 3.0L V6. I just had a Super 40 flowmaster professionally installed today. I never tried revving my engine in neutral before, but I tried today so I could hear what the new...


Hello there,

This is a normal operation, all your doing is hitting the rev limiter. It's there to protect the engine from over revving. The Powertrain Control Module or PCM cuts fuel to the engine intermittently to keep the engine from revving past a predetermined RPM when in "neutral", and in "park" if it's an automatic. Just in case something like a foreign object or a small child or animal were to inadvertently depress the accelerator pedal and rev the engine too high and damage the engine in result. I hope this info helps, and just for peace of mind, I am a Master Certified Ford Technician. Enjoy your new exhaust!! I'm sure it sounds great!!

My dodge dakota it idles below 1000 rpms and it sounds like its about to stall. and if i rev it up and then let off it will stall instantly. when i am driving from first gear to second it goes up to 4000...


It is actually hard to say without actually seeing the vehicle, but the target speed for your engine idle is around 750 RPM. The stalling after revving kind of depends on how high you are revving it and whether the engine is at operating temperature or not. This may be normal. Then again, it could be that the Idle Air Control (IAC) is not working properly.

The shifting from first to second at 4000 RPM sounds like a completely separate problem. This could be due to low transmission fluid level, sticking shift control solenoids, or possibly even a malfunctioning Vehicle Speed Sensor.

If the Check Engine light is on, have that checked first.

In neutral car is not going more then 4000 rpm


The 300M is equiped with a rev-limiter. The technology is designed to protect the engine. It keeps you from blowing it up when it has no load on it...If it is driving and shifting ok, and you have no check engine light on...there is nothing wrong.
Why would want to rev the engine past 4000 rpm in neutral anyway? Max torque comes in around 3950 RPM...
If you keep reving it up in neutral you might throw the computer in to LIMP mode, then you wont go no where.
Hope this answers your question...

Wont rev past 4500rpm


I hade this proble on my 86. It may not be your same problem but check the connection plugs on your secondary injectors the heat from the engine worped the connectors preventing a tight fit so they would come loose and at about 4500 rpm the car would bog cause of lak of fuel.. or your secondary injector are bad
