Sounds like this is normal. It is warming up the motor. If it's more than 1500RPM after you start it up, you might want to have it checked. It should idle around 500 to 800RPM

RPM high n everytime i shift then car speed keeps on going fast n i dont even step onto the accelerator so i can add more speed of stay on a constant speed


You have to change your clutch kit. I just had this issue and after changing it it runs smooth again.
Just to confirm, you shift gear up, your engine roars (goes up to 4000 or more RPM) but doesn't gain speed until few seconds later after the RPM is back to normal.
If so that's the clutch plate causing the issue.

2004 Chrysler Crossfire 25,000 mls auto, road hum noise


MOST of the hums after a while come from the diff as the back axle does the driving and almost all its life runs the same way except when going in reverse ,is the rear diff meshing and worn on both the crownwheel and the pinion and the humming gets slightly louder the faster you go and almost goes when almost stopped and this can also be the slight vibration you get so get the diff oil drained and refilled and check if there is any metal in the oil when drained if so thats your problem But it will last for years like that..Let me know how you get on RON

I purchased an hyundai terracan turbo 2.9 diesel 2003 last year. I was very impressed with its comfort, power etc. However I soon noticed an unusual noise arising from the engine while at a good speed...


this may be something you might check ? the fact that the noise sounds like humming? on rapid decelleration from speed ? as you release throttle from speed downhill the turbo revs drop off and pressured air is reduced into manifold ok ? but the engine speed/rotation is then driven by the drive from the roadwheels/transmission therefor the engine is vacuum caused by induction into manifold is still on increase but due to possible induction hose from turbo to manifold ? this hose may? be collapsing /sucking together thus creating air restriction to engine if this does happen ? then the symptom of labouring and sound of humming you describe may be what is happening? for your info the cause of over rev of engine especially on decelleration from high speed could cause the pistons to catch ip with the valves and bend them? this is a danger to avoid hope this helps?
