Car idling too fast Hey,
I just installed LT headers and y-pipe and now I guess the car is getting too much air. I purchased HPtuners to Tune my car but I was wondering if there was a "quick" fix to slow down the RPM's so I dont bang into Drive. Anyone have any ideas??
Thanks!
Evan

Just like I suggested in this thread you posted about the same exact problem https://ls1tech.com/forums/pcm-diagnostics-tuning/972319-just-installed-headers-ory-need-help-please.html
Find out why it's idling too high before you tune it.
You're creating a nightmare for yourself if you do nothing but install headers and a Y, get a high idle and use HPTuners to lower it.
There is a mechanical problem with the car, whether it's a hose off (like the brake booster hose?) or a broken temp sensor, tuning it isn't going to do ****.
Scan it with HPTuners and post the scan file, someone here will figure it out for you..

See if you follow the link I put up where he posted the same question, you'd find the year when he said this Fun chasing links around isn't it?

I agree with 9000th01ss, there has gotta be somthing wrong. By tuning it, it will make the car idle lower but the original problem will still exist.

Anyway, back on topic....
99.9% of the time, it's the EGR tube leaking on the top of the intake. Tighten it. it's something like a 21mm size.

So im pretty much a very big newb.. After I installed my headers+ory+SLP LM1 my car is running pretty fast, it settles down to 1000 rpm but fluctuates to 1400 rpm. Is this because its getting too much air? or is it injecting more fuel, running rich? I just ordered HPTuners and I wanna make it a good driver. What I'm asking is when I get the program 1st I have to save my current VCM in a binary file because its a 1998? I dont know what a binary file even is...And what would the file be considered to tune the Air/Fuel Mixture, seeing that that is the problem? or should I lower the Idle???
Sorry for the length but I'm a pretty big newb when it comes to tuning...
I realize this is probably a common problem since its only full exhaust but was wondering if anyone had quick answers...
Any help is appreciated.

and fwiw, I've had similar idle issues because of exhaust leaks. The ones way down stream in the exhaust system wont mess with your tune, but the ones by the collector, close to the O2 sensor, can really throw things off. I got tired of screwing with clamps, so its welded solid now. No clamps, no leaks, no issues.

And the EGR had nothing to do with anything you posted, I didn't even read your posts. I figured out it was an EGR car cause he said it's a 98. After 2000, they took it away.
why are you trying to bust my *****? Leave me alone.

I really don't know why you're jocking all this guy's threads, but whatever. I usually dont click links other people post in someone else' thread. I was asking HIM what year it was, not you.

We're all here to help each other out right. Am I trying too hard?

And then check this out a third thread, same guy, same problem.
https://ls1tech.com/forums/pcm-diagnostics-tuning/973849-quick-hp-tuners-question.html
In this one he said he stuffed a rag in the egr hole in the intake. So I guess we're all wasting our time here. Now thats bullshit.
