i got these codes today from the ecu.
0707-downstream oxygen sensor or circuit fault
0304-knock sensor or circuit fault

could knock sensor fix my jerking engine, since the ecu did not give any of the cylinder misfire codes.

where is the downstream oxygen sensor located at?

thank you

QUICK !!!!read the sticky post engine code.Bill will get YOU!!

 

I had those exact codes about a week ago while I was on vacation. I wsa told that the knock sensor was probably set off by the downstream O2 sensor. You had better hope so because changing the knock sensor is a MAJOR pain in the you know what! I reset my ECU and put in new gas and some Octane booster and the car ran fine---no problems and no new codes.
