Ok so here's the deal,
l got a all motor lsvtec set up.
motor worked great after a tune.
running innovate wideband o2
tuned on neptune

one day the o2 starts reading some wide crazy readings and then ***** off altogether.
Now it will read 22.4 no matter what position the throttle is in.
ive tried recal numerous times no luck.

the car obviously runs like a bag of **** with the o2 that way.
before completely blaming the o2 for the problems I'm about to mention I've already checked
MAP
TPs
iacv
bought new plugs wires cap and button.

heres whats going on
start the car it idles up to 2000k steady idle, normal idle is 1100-1000 on start up.
hesitates like a mo fo spitting and going on,
if you switch the TPS and map plugs around it goes to normal idle but the hesitation is worse. But idles very nicely.

can this ALL be because of the bad o2 reading..?.?

a new o2 will be here tomorrow but I want to know if can check or try anything else before it gets here......?
im trying to make it to a car show in 3 days so time is of the essence....

Please help, I've already done a lot of reading but can't find an answer....
thanks in advance!
