Message	Warm up engine until temp gauge in normal range. Find the EGR located at the back of the engine near the firewall. Try to get to it by working your hand in from the battery side (not easy). Feel under and push up to raise the plunger. At idle the engine should stumble. This tells you passages are clear. Next blip the throttle and make sure it raises by itself when above idle. If it doesn't, need to check for bad EGR, solenoid, or problem with vacuum hoses. There are other ways to check EGR function though the vacuum lines. The above check is quicker.
