Inspect the coil for cracks or signs of shortage!! Also if there is oil leaking into the distributor, this will cause the coil to burn.

Have you had this problem long? is there a check engine light on? have you done any new repairs and then the problem come to be?

o2 sensor, or some other emmisions sensor

Locate the brakes Booster and some where below the Mastercylinder should be the connection for this light , maybe the pipe has popped out.

Go to Autozone and have your current EGR Valve, removed from the car, tested and they will determine if it is defective. They tested 2 for me, and neither was a replace, just a clean and they worked great. If they don't have a brand that suits your wants, just test it, then buy the new somewhere else, no commitment to buy.
The most common problem with these EGR valves is they get plugged up from carbon build up. Best way to test it is with a little hand held vacuum pump. Hook it up to the EGR valve and with the engine running at idle and squeeze the vacc pump handle a couple times to open the EGR valve. That should kill the engine. If it dosent, the EGR valve is probably plugged up. At that point you'll have to take it off and clean the carbon out. Even if you have your mechanic check into it, it shouldnt be that expensive to remove it and clean it out or replace it.

Good Luck and hope this helps: Oh and I think theres two EGR.. check the one on the bottom of the engine to. I am not sure but i think there are two EGR valves on your camery.
