ok about 8 mouth ago my check engine light went on after cleaning my engine bay on my 96 240sx , i didnt think much about it i thought i must of mess up a sensor or something. 2 month after that went off i thought i was ok for now then it came back on after a week or so then i decide to check what it was. the diagnostic said knock sensor, p440 evap p1447 evap i also got a second opinion and he said it was just knock sensor. Now im trying to get my engine light off so i replace the knock sensor. then i found out the that the charcoal canister gave out and it clogged out all my vacuum line that lead to the carbon canister. so i replace the charcoal and used an air pressure to try to clear out the vacuum line that leads all the way to the back. this morning i went to check the vacuum line and it was dropping charcoal aging wtf!? did my charcoal canister gave out aging? how do i get rid of the check engine light? did i do more damage to my engine waiting so long?
