sometimes after driving I engage the clutch the idel goes down to about 2/3000 RPM, and slowlly goes up, it does not shut off or trys to stall, and slowly goes up to about 5000 RPM. I know normal RPM should be 7000, the car does not shake, smoke, make funny noises and gives good milage. Is this normal , fresh Tune up plugs, cap rotor, air filter . i looked into the EGR valve. Am I right? Please help. thanks
