Hey guys new to this site. but i have a 2000 z28 with about 38,000 mile on it that i bought last febuary. well anyways all of sudden i go to start my car this morning and it wouldn't idle rite. it would go to 400 ..seem like its about to die and then jump to 600. It did throw a code at me last week for a bad o2 .. i had the code deleted but i was told that if the ses light came on i should get it changed . only reason i havent gotten changed is becuase money.any help would be awesome cuz this thing is really stressing me out. Thanks

...ps sorry if this a bit confusing im at work and just stressed.

When my car had erratic idling problems in the past, I've always fixed by cleaning out the Inlet Air Control Valve. It's on the side of the throttle body. Take it off and clean it with carb cleaner.

IAC? fuel pump?

replace the O2 ...
if your DELETED it , it will not comeback...but you will still have a bad O2...

if that does not fix it(but i think it will)

then i would look at cleaing your IAC.... not the IACV....
IAC=idle air controler...

Thanks for the correction. Idle Air Controller, not Inlet Air Control. However, it still is a valve.

Do you know what code it was or what it said? bank 1 or bank 2, ring any bells? if it was your rear O2's then its ok to delete them, but your fronts is a no no, i say go cheapest first, clean your IAC valve, if that doesnt work, fuel filter, then if that doesnt work replace the O2 sensor, those things are like 110 bucks from GM, but im sure you can find some on ebay for cheaper, or if you know someone w/hp tuners have them delete your rear o2's and replace them with the ones up front, they are interchangeable, although i dont know if the wireing is long enough,
