i have it off and cleaned question is, can you clean where you took it off at? thats still connected to the engine. i'm talkin about the tube looking down at the egr and everything can you spray carb cleaner in there or is that a no no? cause i'm currently pulling a egr insufficent flow code and i'm trying to clean all that up, or can someone tell me how to clean the egr sensor?
