Check Engine

Ok, this is really starting to pi$$ me off. Every now and then the check engine light cimes on. Sometime while it is on the road the car will surge, feels like I'm tapping the brake then pressing the gas. While the light is on and I'm ideling<--(is that how you spell it.) at 700 rpms the ideal will drop down to 500 rpms then back up to 700 hold for a bit then do it a few more times. When i run the codes the damn light won't go on and I get no codes. Any ideas guys? Any help would be great. If you need any other info let me know thanks

Check for vaccum leaks, and check your fuel pressure. And you can check for leaks while the idle is idling ;) ;)
Do you know how to do all this?
 
Yes I do, I have tried before with some starter fluid but just sprayed over the engine real quick. I think you may be right because my car is a little louder than before. Thanks for the input
Any other ideas would be great thanks
