hey anyone know much about o2 sensors goin in the v6? i had a search and o2 was too common so didnt find much. my car is mssing pretty bad at times but not at others and a mate reckons its probably the o2 sensor and possibly the knock sensor? i dunno bout mechanics that much but ive read a bit about peoples o2 sensors goin so just wondering if its the elikely cause and how much to rectify it, cheers

If it's missing I would say check your spark plugs.leads/coil/dizzy.

air flow sensor mabey?

Oil Temperature Sensor (Refer 23-2-18) . . . . . . . . . . . . . . . . . . . . Resistance varies wilh Lempcrat~~rc
Throttle Position Sensor Resistance . . . . . . . . . . . . . . . . . . . . . . . . 3.5 to 6.5 kOhms

still trying to find other EFI component electronic specs

at a guess Mrmacomouto and perry have it covered

the o2 sensor on yours should have two wires
wont be your problem it only works on a low voltage range

doesnt sound like O2 sensor dude, check ignition first. dizzy to plugs. O2 sensor shouldnt affect detonation timing in any way

ok fair enough, thats what my mate seemed to think but i'll take that on board, i doubt it is leads or plugs cos they were done just last year, will hafta look into the rest. its just weird tho cos sometimes its fine but it can miss really bad at times, like if i wanna give it a bit it can rev from say 3000 to 5000ish and not accelerate at all, it seems to only miss under load aswell if that helps

pull the leads off and give them a spray with crc/wd40/contact cleaner and put them back on.

Make sure there on well.
