Hello, First, check that the idle air control valve is functioning and not clogged. Next, you should do the same for the EGR valve. There is a chance of fuel delivery issues, so if the EGR and idle air control valve are in good working order, test fuel line pressure. If there is a check engine light visible, scan for codes with an OBD-1 scan tool.
