Best Answer

Take the Vac line off of the EGR. If the engine runs good then the EGR is bad, Or the cheaper fix, The vacuum control valve. Located in the middle of the block at the rear. You can follow the vac line around the rear of the motor to the controller. To test the vac control take the elect plug off of it, Start it up, If you still have vacuum at the EGR line, The vacuum control is bad. It sells for around $40.00.
