Get some throttle body cleaner. Remove throttle body and dismantle it and clean all parts. Remove Idle Air Control Valve and clean that also. Check all hoses for vacuum leaks. Remove PVC and spray some cleaner through it. See if you notice a difference. If car still acting up, unplug the EGR and see if that makes a difference.

I've try'd all that didn't help


Okay, when you say flouting what exactly do you mean? Flouting is totally the wrong word. Do you mean your RPM's are fluctuating from high to low?

This happens only when in In gear at 4000 rpm it bounces up and down


I hate to suggest replacing parts on your car because they are very expensive for that model. Do you have the check engine light on? Have you replace the crank sensor?

No light I'll have it checKed out I've only had the car about 2 month's


The only other part I can suggest is the MAP sensor. A bad MAP sensor does cause the engine to surge. Have you replaced or tested it?

No I'm going in to have my car tested today thanks for your help


Post back with the solution. So many people just end threads and never post back what caused the problem or how they fixed it. Thanks!

    When I press the accelerator the car starts a slight rumble between 1000 and 1500. The car runs perfectly fine after that and has a perfect idle. Sounds like it is coming from the glove box area.
