- 02 VX SS Manual
Hi all, i'm getting a check engine light on my LS1 VX. Scanned it up to be P0327 - Knock Sensor Circuit Front Sensor.
Code disappears when car is turned off and comes back on after about 1 min of driving when hot, takes about 10 mins when cold. I can feel it pull timing under acceleration and feels like its hesitating and low on power.
- I have replaced the knock sensors and harness. The harness isn't catching on anything so pretty confident to rule this out.
- Replaced fuel filter (assuming its pulling timing from running lean)
What else could it be? Is it possible its bad 02 sensors? or does the computer throw a code for this?
Is it possible its a coolant temperature sensor? May have been coincidence, but i saw my OBD reader read 41 degrees coolant intermittently and the light came on. But I wasn't able to replicate this after and the light kept coming on.
All help is appreciated, thank you
