Well got my car home,my mom went out this morning and it started.So she drove it and I changed the main relay.But it was idling to high so I unplugged the eacv plug and adjusted the idle to 800,plug the valve back in and now it's surging up and down.I have no idea why it's doing this,anybody have any ideas.
