I have my engine light on amost everytime I drive. It shows the same code everytime which is 12-EGR system. Well I've been to mechanic about 4 times and he can't find out what's wrong. He replaced, oxygen sensor and EGR valve, but the light still comes on. I don't have problem with driving the car, except that it feels like it accelares a little bit slower and stalls on idle. The light will come on usually when I am driving fast, as soon as I switch to 5th gear and speed up, or sometimes when I try to speed up on the up hill. Can you give me some idea what it is that I need to fix because I have spent a good amount of money already and I don't want to spend more and not get it fixed again. Also is it possible for me to fix it by myself. Maybe a link to something that explains how. Thanx a lot!

OK nobody is answering my question but I have some more details. Hopefully somebody can help. I took my car to mechanic AGAIN (different place this time) and they checked the code and it said insufficient EGR valve lift. They checked and said the carbon deposits needed to be clean so they cleaned them. After that I really noticed that my car drove different. It accelarated much faster and didn't stall anymore. But the light came back on. And now it comes on when I switch to 4th gear. I don't know what to do. I checked the code myself and it is still the egr system code. Please guys help me with that. Why can't I find a mechanic that knows what he is doing.

Ok. The test for the system is pretty cut and dry. First you can apply vacuum to the valve and see if the idle changes(it should stall or almost stall) if thats ok then check vacuum to the egr solenoid there should be manifold vacuum there. Next energize the solenoid by jumping power and ground to it. It should click and vacuum should pass through it. Thats it. Hope this helps
