what will unplugging the o2 sensor do?

i thought the O2 sensor was only at idle an shouldnt affect how the car accelerated.

If the cat was blocked, wouldnt it hunt and have lack of power at all times, including when its cold?

Thanks for the advice,

i have cleaned the iacv (bitch of a job and didnt try to take off the sealant). Put it back in and now it runs on (only drove it for 20minutes) i noticed when i turn on the AC the revs drop :S

any ideas?

cheers

Well, the IACV is meant to control your airflow at Idle, meaning if you turn on things that put load on your engine at idle (i.e. AC), it's going to change your idle speed to match. But for your issue, a good cleaning on the Idle Control Screw on your IACV will usually fix idle hunting. You probably noticed the tip of the screw had a fair bit of caked-on crud on the tip when you pulled the unit off, right?

    • Maybe I used the wrong sandwich plate as well. Used one piece instead of two piece.  
    • Y'know what, after reading a topic on a 360kw build using a nistune (who ended up going LINK), im now considering a LINK over a nistune. The engine protection alone would probably be worth it. And id like to learn to tune so would be nice to have that safe guard. Which means i probably wont need a boost controller then, or the R35 MAF.  Becoming a bit of a blog now but oh wells. As mentioned previously, the goal is around 300kw, for a daily driver. Will be looking at fitting a highflow turbo or similar (something that doesnt require downpipes, manifolds etc to be changed out) when the current stock gives out or the money for it is there. 
    • Thanks guys. Are you meant to tighten the converter bolts through the starter motor hole? Think my plate between gearbox and engine is one piece. Im heading up there tomorrow.
    • Picked my tailshaft up yesterday arv!! Test fit it and because they've gone to a ford centre bearing and CV I had to modify the mounting bracket a little bit. 5mm of each side and she went up into position and fits well. It has a 1350 uni and flange on the gearbox end so it should be plenty strong!  Got stuck in this morning and started on the wiring mess. Cut out all the wires not required that go to the body connector and cut the engine harness out. Need to go through and work out which ones I need to keep and rewire into the new ecu. Should save a small amount of weight as well. I'd love to get in and rip the dash and everything out to completely remove wiring but cbf.  Next up was the power harness for alternator, starter etc. It has a few connectors from factory that run out of it. Cut it all apart and removed what was no longer required and put some new corro and taped it all back up and bolted it all back into place.  After that I worked out where I can mount the new flex sensor. Found a couple of factory bolt holes and drilled a new hole on the bracket to suit. Need to go get a few fittings and adapters tomorrow so I can keep going.   
    • Nah, im after the more newer looking, one with the OLED display
