Question
Hi I replaced my lower intake gasket an my check engine light has been on ever since. I tride to pass emitions when it turned off for half a day. Now I'm getting trouble codes P0507 ICS RPM higher then expected,P1404 manufacturer specific code "wich I cann't find the answer to". So any type of help would be great. :)
Hi Jess.... make sure that you plugged everything back in after you changed intake gasket...if everything ok... clear the codes and let computer relearn...check that you don't have any vacum leaks as well...if all is back together right and nothing unplugged it should clear up...hope this helps
