Hey all! Newbie ‘99 986 Boxster owner, I’m getting a reoccurring CEL with P0326, P1123, P1125. I’ve cleared it once and drove for a bit with no issue. Today after a bit of driving and giving it a bit more throttle, this code combo popped up again. I did notice some hesitation at 5-6k rpm. I’m still on the first tank of gas since purchase and apparently it was sitting for a bit.

For the P1123 and P1125, I’m thinking of trying some fuel injector cleaner. Possibly a fuel filter change. Is this a good starting point?

Looking for some advice on the P0326 - Knock sensor 1. This one sounds scary, but is it just that there is an issue with the sensor? Or, caused by the other codes? Or did it detect a knock which sounds bad.
