EDIT-

Have you driven the car around for a little bit?

nemss1

ya, ive driven it around a couple of times. my car only started idling at a grand after i removed my rear o2's, so i wldnt think any of my other mods caused it. can rear o2's do this?

No they're not suppose to. It's possible something else could be causing it and it's a coincidence.

Best way to find out if thats whats causing it is to put the rear 02's back in, and see if it goes away. If it goes away, thats your problem and the PCM will require a tune to correct it. Usually however, removing the rear 02's only throws an SES code and thats it.

what he said... i removed my rear o2's, and no change in idle.

Replace the 02s and see what happens

what is the stock idle supposed to be in park?

i have new front o2's, fuel filter, plugs and wires

nemss1

would a lean or rich issue cause me to idle higher?

besch

im having the same issue after putting headers in.

do you have LT's?? check all of your plugs/wires.. and clean your MAF

nemss1

no, im still running the stock manifolds on an ORY. new plugs and wires. wires snug. should i mess wit the idle screw?

yea, you can... yuou wont have to turn it but maybe one turn... turn it, and then drive down the road, come back and check your idle..

it wouldnt hurt if that doesnt help to replace spark plugs... thats usually the problem...

i run rich and also idle high.. although my mods are different than yours.

nemss1

could i have already fouled them if im running rich? they were replaced a month ago along with front o2's, fuel filter and wires

One suggestion. I've seen you posting basically the same **** all over the place here. Keep it to one or two posts for consistancy. It saves people time when they answer a question. If people here see you put up a mess of questions all over the place and are getting input from one person saying do this and another saying do something different, it kind of makes me at least hesitant to reply because it looks like a mess of information, and that alone is confusing you, making you try different things and adding more confusion. Pretty soon you're spiraling in a mess and ready to give up.
But thats just my opinion.

nemss1

ok i understand, sorry. ya i could see where it would cause me confusion. the last thing id wanna do, is give up lol. gotta get the car running right again

i believe the idle in park is like 600-650

Perfect example of what I just posted above.

Look at this thread about idle. https://ls1tech.com/forums/generation-iii-external-engine/973318-what-normal-idle-stock.html

I cut and posted these screen shots of factory programmed idle speeds for each varying condition. Thats how it's programmed, now you get a reply with an off the wall 'I think' guess.
I put some time in replying to that and now it feels like for nothing. So.....
Good luck, hopefully you can wrap it up in one big pile of info, sort through it and make something of it all.

nemss1

well id definitly go off of the datasheet instead of an 'i think' answer
