You can get a free scan done at your local Autozone parts outlet to retrieve the code. Without the code, we are not sure it the problem is due to clogging or a fault with the components.
The EGR solenoid location is Item # 17. The EGR valve is connected by the vacumn hose. I do not have any diagram of the valve to show you. Look out for a valve that looks like a cage cased item. The solenoid is as in diagram.
EGR Valve Check
Remove EGR valve and check for sticking, carbon deposits or other debris. Clean with suitable solvent as necessary and ensure valve seats properly. Using a vacuum pump, apply 20 in. Hg (67 kPa) vacuum to EGR valve. Vacuum should hold. Apply 1.6 in. Hg (5 kPa) vacuum or less and blow into one EGR port. Air should not blow out of other port. Apply 8.7 in. Hg (29 kPa) vacuum or more and blow into one EGR port. Air should blow out of other port. If EGR valve does not test as specified, replace EGR valve.
Check EGR port for restriction. If carbon deposits are clogging the port, use suitable wire to clear. Carb cleaner can help soften the carbon deposits.
