I have a 2000 sentra gxe. whenever i am at a stop my car will idle down to like 250-500 rpms and then go back up to about 750, if it doesnt die. if i give it a little gas then let it idel down it will do the same thing. i saw a thread on this same problem and someone said the cleaneded their egr valve and throttle body. whats the best way go about cleaning the egr valve and throttle body
