I have the basic conzult (shareware), what should the bar that says O2 read? Mine just stays at 0.5 and never seems to change when revving etc.....

0.05 volts actually...

They don't actually send any reading until the car is warmed up.

 

If they are still giving this reading once warm, you need new ones.

They should fluctuate on acceleration once warm.

yes this is true but also could be the loom ...this happend to me i put new loom in & hey presto they work!!!

I've got a new loom, and the car was fully warmed up, so maybe need new ones, eeee, aah well, at least there's not much else that needs replacing as i've done most everything! Will check connections first tho....

Sorry to jump in but ive got a set for sale genuine nissan less than a 1000 miles.

 

Cheers

ok mate, cheers, will have a mess with em tomorrow, the car is running rich, and if revved, sometimes drops to 5, and gives pops and bangs out of the exhaust, and tickover is a bit lumpy, so they could be cream crackered.... I'm in the process of having my teeth done, have to wear a retainer, which cost 150 quid, and about an hour ago, took it out to eat my tea, and my dog ate most of it! not happy about it! so gonna have to shell out for a new one asap, but i'll be in touch if i need em matey, cheers....
