Check Coolant temperature sensor

Do you have a CEL?

Are you using stock ECU?

[nice240]

this is my first swap. i have a s13 sr20det but it has a s15 t28 turbo on it. and stock ecu could that be an issue and also it was reading a code 34 knock sensor.

[nice240]

just drove it with the o2 not plugged in and it reads a code 34 knock sensor. why would it run better without the o2 plugged in and read knock sensor? could it just be the knock sensor? And the ecu doesnt read a bad o2 when its not plugged in. but remember when the brand new or old o2 sensor is plugged in , it runs real shitty and sketchy and can hardly drive . only a code 34 knock sensor comes up when i leave the o2 plugged in and check the codes. so idk, please help me out
