Checked fault codes?

Dud 02 sensor or water temp sensor?

thanks gtrboyy ive got a new temp sensor. ive also replaced the map sensor and still nothing :(. im thinking its the ecu hi_ryder but its got a replacement ecu done back in 2004 ish how likely is it that its gone again? I know it was originally replaced because the engine was surging? its from australia computer engineering or something like that, opinions?

Dunno mate maybe try another ecu if you know it's good.

If changed CAS can only think earths if no fault codes are popping up.

Mine was running rich as hell when got it codes all clear....finally cel light came on it popped up fault codes for 02 sensor & ecu error + lean code....disconnected battery,changed 02 sensor & all good
