Welcome to the Michigan FBody Association website.
The Michigan FBody Association is a centralized website for FBody enthusiasts to discuss what's going on in the Michigan area. MiFbody.com was created to allow for an easy one-stop place to find out what's going on in Michigan as far as FBody events, to find out what clubs are available in your immediate area, and for an easy place to post classifieds for items you want to sell! Our goal was to create a more close-knit community of FBody enthusiasts in the state of Michigan, and to bring Camaro and Firebird enthusiasts alike together for some amazing FBody events!
The most important thing to know about the Michigan FBody Association is that we are NOT a club! The Michigan FBody Association is open to everyone, and is a community. Thus, we will have get togethers, casual cruises, events, and such like that, but this is not an exclusive club and it's 100% free to join this site! So what are you waiting for? Register now!

I know of some stock rockers that have seen close to 7k rpm many times... No issue.
They will take it no problem but the bearings will come apart over time. Happened to Jeff before. Hence the reason they make the torunion upgrade for them.
Stock LS rockers have been to 8,000 RPM and .650 lift no problem.

Maybe they were blowing smoke up my ass, but Livernois told me that gm made revisions on the stockers, almost eliminating the possibility of this happening.
i replaced mine with my stockers eith new stockers... thats what they recommended.

They may have. At Katech we use stock rockers in everything from 450hp street engines to 24 hour endurance race engines. They are all obviously brand new tho.
Yellow springs are only good to .550 lift. Not saying people don't try and use them on a TR224.
Well, .551 at least (02-04 Z06 cam)
I'm with you, definitely wouldn't recommend it, but many with lower duration and under .570 lift have had zero problem. Mathematically, they coil bind at .610 lift at 1.80" installed height. Subtracting .050 for a buffer nets .560 safe lift. But the soft seat pressure, actual install height on non sodium filled valves, etc. make them a poor choice for anything over .550, long duration, or will see high revs.
Completely redid the PCV system on my car. All new hose, PCV valve, and Y/T adapter. Unfortunately no change in my goofy idle. When driving and I push the clutch in, the car goes to 1800 rpm until I come to a complete stop. 99.9% there are no vacuums leaks.
Up near the cowl as in not actually in the intake? The IAT sensor is there for a reason.
Yep and I know this. He tried every other trick in the book, trust me the kid probably has 500 tunes under his belt on that damn car.
Someone on HPTuners forum said it fixed it for them, it fixed it for Jon too.
Found something on it with a quick google search:
To correct this you need to relocate the IAT sensor or upgrade to a 01-up OS like SSute01 said. Your '99 is IAT based only and when the IAT heat soaks due to radiator heat and underhood heat it will falsly report high temp readings to the PCM. The air isn't actually that warm... Moving the IAT sensor into the intake manifold or in front of the radiator to where it can't heat soak will cure alot of your issue.
EDIT: i just reread Nate's description of the issue I don't think IAT is anything to do with a high idle. If its "hunting" for idle, id check it though.

IAC need to be replaced?
I can head out towards you with my HP Tuners next week, we can take a look and see what is going on.
If its not a vacuum leak, and since we alreadty did a reset on your IAC, your IAC counts are probably off in the tune. The only way to really hone them in is with tuning.
The only thing we havn't tried is another IAC. Another thing we could try is unlplugging the IAC and see if it is still acts the same way.If the problem goes away its most likly your IAC counts.
