Hi guys,



I have just turned off the O2 sensor from the power fc and it seems like my surging idle problem is somewhat solved.. can i run it like this..



Is it a permanent solution?

you can run wothout the O2...



your car will just run a little dirtier i think

Very bad idea. The reason you have a pfc is to help monitor and adjust your engines settings. Why not tune it properly? You'll get better gas mileage, more power and you'll have less chance of detonating an engine.

you dont need the o2 for this..

I have been running without a stock O2 sensor for over 2 years now with no ill effects. Gas Mileage wasn't affected too much either. I did get slightly less gas mileage, but that could be easily fixed with a decent tuning on the lower end. Also note...I have a wideband 02 to do the tuning.

I intend on disconnecting the O2 semi-permanently after I get it tuned out with a wideband.

I leave mine off as well. Its alot better then the surging and buying a new o2 sensor to fix that surging.
