Ok, I was just coming down the newcastle freeway at 115kph on cruise, light came on(code 63 LH O2 sensor no signal) I switched off cruise, slowly rolled to 100kph light went out then back on cruise, light came on etc, etc, etc.
While car was at a fixed throttle position light came on when I was rollin down hills, etc light went off, this happened all the way home. Please can someone tell me WTF is goin on.This only started to happen after drivin 300 k's or so it didn't happen on the way up the coast, but it did happen about 4 weeks ago on same trip.
Cheers

My first response would be to check connections to the O2 sensor, then I'd run a can of injector cleaner thru the system although if the ECU detects "no signal" from the sensor you'd imagine it's an electrical problem.
