Anyone can tell me what else can i do to find the problem on the EGR, this is what i done so far, i replaced all 3 O2 sensor upper and downstream , cleaned the EGR Valve real good, replaced the top sensor on the EGR including the TEMP sensor. i still have the engine light on after reseting. I haven't replace the VSV yet since i'm not sure which one is the one. On the diagram i seeing 3 VSV hiden on by the top of the engine plastic cover. Can some one give some guidance ref. this issue.
Thank you Ace....

more then likely the EGR port going into the intake is stopped up with carbon pull valve off and see if you have alot of vacuum there *enough to either cut car off or have it idle up about 700 rpms when removed. if thats the case easiest way to fix it is take intake off and clean it out
