car just threw this code, i have had a bad pre cat for a while, 19000 miles on the 03 wrx. is this bad what do i do?
my brother was driving it, wasnt in the car, said he was backing out and it popped up. I cleared the code, drove it going 50ish give or take for 5-10 miles car was driving fine, and cant get it to come back up, but im hearing this slightly wierd intermittent sound coming from the drivers side of the engine, only at idle, when i rev it up i cant hear it, but its some kind squeek and clunk combination lol. any ideas im scared for my engine.
completely stock car, and i cant smell anything funny
just put 20 more miles on it and it wont come on again
