Buy the extensions before you attempt to run the car. DO NOT try and run the car without the O2's where they should be.

Bayer is right, DON'T RUN IT. Your friends car may be fine now but he may have damaged something that isn't showing yet. Your front O2's monitor your F/A ratio and can cause your car to run to lean or rich if not functioning properly, causing cat damage, spark plug failure etc..... Your O2's keep the balance in your motor. WAIT and get your extentions, you'll thank us in the long run!!

Not a good idea but unplug the maf so it is running in closed loop..

If you cant wait for the extentions, and you feel like you can do some rewireing, you can change your rear O2s to your front O2s by repinning your ECM harness, here is a website that has the pin info:

http://www.lt1swap.com/wiringharness.htm

You will just need to change the pins for the front set to the rear set and then plug your O2s in the rear set.

Another way is to run over to a parts store that has the corvette style O2s that are long enough to reach from your front O2 harness.

I like this idea. The safest option. And don't you mean open loop?

Better run pig rich than too lean. This should only be done to limp the car a short distance, IMO.

I'm with bayer on this one, if you care about your engine, don't run it without o2 sensors so i can properly adjust the A/F ratio. Why risk screwing something up when doing it the right way is cheap?

If you drive it normal it will be fine....without the 02's hooked up its not gonna go into closed loop anyway so leave the maf hooked up. DON"T RUN IT HARD!

I'd cut the female plug and wire out of the harness for the rear O2's. Then cut the male plug off the rear O2's. Solder the two together with heat shrink on them and you have homemade extensions for free.
