Po400 WTf
okay guys, here is my question i am pretty familiar with the ls1 but not so much on the lt1,
my cousin has a 95z and he just had the o2 sensors replaced per the dealership, i told him to just let me look at it but i guess he couldnt wait, anyways now that he paid them to replace the o2's and a few other sensors his ses light came back on as a po400,
which is low egr flow, and normally when this happens i would just take of the egr and clean it which is what im gonna do, and check the vacuum line gooing to it, but i was wondering if anyone else on this board has had this problem and what was the issue,
thanks for your help, im sure i can fix it i just wanna save time and not beat around the bush,

sounds like a good thing to check. if the car is only driven short distances there could be a little carbon build up.
