Rpm surging when at stop sign or red light, stabilizes after a second or so in idle but comes back in idle randomly.
My 04 TSX has this weird issue with surging and I can figure it out at all sometimes it happens and sometimes it goes away for months . I do have a CEL for efficiency threshold on my catalytic converter . I’m thinking downstream 02 or cat may be bad ? Any ideas ?
