The EGR should NOT be recieving a vacuum signal at idle. Test the idle air control motor .What is the idle RPM in park with A/C off? does the idle change slightly when you turn the A/C on?

rpm with ac off is 500 turn on ac moves to 1000, checked for vac leaks changed map sensor same thing it feel like the trasmissiom has a lot of torke on the motor when put in gear at idel i can tell the motor mount are bad.one thing at a time.

Change broken motor mount(s) and then check IAC (idle air control) valve. If you've had connectors off at the throttle body , check and make sure the TPS plug is in securely. AND just to be sure --the check engine light is NOT on correct?
