First check if the fuel filter is clean, then check the pump for wear and tear or clogging , also while you're at it it would be a good idea to see if the carb jets are clean.

I got a 2002 Taurus n it runs fine upon hard acceleration until 3000 rpm to 4000 above that it's fine again, in between 3 n 4000 it spits n sputters like a misfire! No check engine light comes on.

That sounds like the camshaft synconizer..They dont oil good and they can squeak like a belt,,usually after a few mins of running..When your at wide open throttle the computer ignores the cam sensor so if it gets a bad signal,,it doesnt see it,,and you get no light...Look at the back of the engines intake..where the wires cross over to the firewall side..Under the throttle body..Listen carefully and see if you can hear it squeaking..Sometimes you have to use a hose to listen

2009 Hyundai accent in 5th gear the RPM is 4000 is this normal? My speed is 115 Klm an hour

No, it is not. You should be around 2500 rpm at 115 Kilometers an hour. Even if you were in 4th it should only be around 3000 rpm. At 115 MPH you would be near the 4000 RPM. Your either running on 3 cylinders or your transmission is in trouble and needs repair.

2000 pontiac grand am 3.4 motor auto trans 4 door.Car starts and drives okay motor seems to stumble slightly between 3000-4000 rpms. with car stopped in park try to rev motor will only go between 3200-4000...

Hi Tom your vehicle is equipped with a Rev limiter it will not allow you to rev the engine above 4000 with the trans in park; as for the first problem you may have one of two things, one of the spark plugs or spark plug wires is bad or you have a flat spot on the throttle positioning sensor in which case have be replaced. Good luck?

If your rpms are going up to 7000 but your not moving your clutch is probally about to go out. Just make sure your clutch cable is not binding or stuck.
