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?
fixed mounts i was i was looking at other auto fix forums and one said it could be the automatic transmission clutch sticking. make any sense
CHECK FOR VACUUM LEAK.
replaced the 2'coupling that go's to a small box next to the main air filter all hoses looks ok.
