Alright guys, i just got my new knock sensor put in and i was out test driving my car. i went to floor it and it would only boost to +1 or +2 and cut out at higher rpm. the check engine light came on for a bit and then went off. i got home pulled the code and it threw a 34. At first i thought boost leak so i checked but nothing. my car is pretty much stock. i search some threads and i got code 34 as fuel cut. why would my car be doing this with no mods?
