Someone elses problem now....
I got my Iroc down at Eric's shop. He and Bennie are gonna' see if they can find out what is wrong with her.
I think I should offer a reward to the first guy that finds out what is wrong.
It looks fast though...even if it runs like crud.

thanks terrell for the compliments.
yeah, I told Bennie he can just keep the thing down there till' he finds out what's wrong.
Will- not the puter...already switched that out (stole eric's)
Del, I can't seem to post good pics of the ride...perhaps eric can snap some off while it's at the shop
I'd like to see a pic from underneath like from under a lift.
those rims ARE scary lookin' huh?...a bit serious...no bling.

well david you adjusted your rocker arms again correct?
when bennie and i were workin on it today, it sounded like your rocker arms were misadjusted or hitting part of the valve covers,
we are gonna check it out more tommorrow
and del i do work on cars when bennie tells me to or i feel like it other than that i dont

Damn, I was hoping it was the computer David. Oh well, hope they find out what's wrong soon and we can see her at the track. Good luck, post some pics when you can.

David I kinda like the whole green / black / grey on red job.
Looks like an IROC with a black eye.
But in all honesty it is a VERY clean car, love those "wheels" but they need billet Camaro caps.

David, pic looks nice, your car looks clean and straight, just needs a little paint, no big deal. It's best to get the mech. issues worked out first then deal with looks, etc.

Well. Eric and I were talking, and we are going to try a different o2 sensor. That is the only thing that hasn't been replaced thus far......

Drove it again and it's still the same. It's not ready until I say so.
It's not the O2.

F up wireing, ya, might be good to replace it with a new one David. I hope it turns out it really is just the O2, keep us updated.

I'm curious as to why you think an O2 sensor could cause a no-start condition? O2 is not looked at until after the engine is running.
Heck, just unplug the darn thing, ECM bias shuold be around 450mv and will run forever that way (albeit with poor a/f ratio).
Does it have spark on no-start? How about injector pulse?
Both thing easy to check with noid lights and spark checker.
Come to think about it, MAF car wil start and run with MAT, TPS, MAF and O2 (probally something else as well) all electrically disconnected. Might get hard to start situation with CTS out of the loop though, never tried it.

this is a drivability diagnose, only in closed loop mode,

Well, there's nothing in this post that says what the problem is, please paste it if you see it.
I did a search on the IROCDADDY's name for posts, and only problem I see him reporting is "drive the car for a bit and get it to operating temp, shut it off and it won't start"...sometimes "chugs".
Sure sounds like a no-start to me? Not drivability.

Here's the only thread I see about him posting a problem, other than a few "how's it work" questions:
https://www.thirdgen.org/techbb2/sho...hreadid=315987
Did he report a different condition to your shop that I don't know about?
I'm here to help. Don't try to put me down.

Damn, chill out a bit Eric, take it easy on 8Mike9.
Anyway, from what I understand his car starts fine on cold starts, and idles fine as well, I have seen and heard it for myself. Once it warms up the cars idle starts to swing from 500 to almost 3000, then it just dies and won't start again until cold. Hope this is somewhat accurate, forgive me if I am wrong David and Eric. Hope this helps you out some 8Mike9.

Thanks Will, but no-one needs to take it easy on me...if ya think I'm a ding-a-ling, cool, just tell me why and show me my mistake
Maybe I missed something about Irocdaddys problem...heck, I've done the "read before you post" thing before too.
Yo Porky...no issues here, huh? As I mentioned before, I'm only here to try to help...even the best shops need a little prodding and poking sometimes.

Will, based on your descripition, I'd take a quick note of the IAC counts and see what they are doing. If fluctauting, then I'd disconnect the IAC and see if it stabalizes. If so, I'd get into idle control parameters.

Good stuff here.
He said "ding-a-ling", haha.
I like how 8Mike9 is prepared and reads before he posts.
Looks like you're makin' Bennie earn his $$ David.
I imagine it's harder to diagnose when it's far from stock.

Irocdaddy, what is the actual problem? Maybe we can kick around a few ideas that get's you on the road? Worst case is that the car stays in the shop, best case is it get on the road.
I think I saw mention that the shop owner (Bennie?) is on the boards, maybe he can post some info as well, and we can toss some ideas his way to lend a hand. I know I'd be wanting it out if it were in my driveway for a few weeks

the problem is an irratic idle at operating temps. do an o2 perfomance test that should tell you if its bad/lazy or good
