Idle Question....Yes I searched..

[classix_stang289]

My car usually idles around 750rpm but now the car idles at 1000rpms and will stay there especially when stopping for a light, stop sign etc. it will idle at 1000rpms. The car feels fine and i have been running the same tune i have always ran which is a dyno tune from chris rose(AM,Tillman)

what the fuck is going on, is this a sign that something is going to give? Yes the throttle body looks pretty damn clean inside.
This just started two days ago

Ask your tuner?

havent yet this just started happening on me, just checking to see if anyone has ran into something like this, thats all. Had my tune in the car for 2yrs now so who knows. I didnt get a chance to check with him yet

I could be wrong, but I feel like I would not worry about that. I know when I switch my tunes (say a perf tune to a race tune) the car does not idle right intill I drive it for a little bit.

Sounds like a vacuum leak.

Beat me to it.

Sounds like a very minor vacuum leak. Check all of the hoses.

Ima have to jump on the minor vacuum leak wagon...

Spray some carb/choke cleaner around all the vacuum lines and the intake manifold while the car is running, if the idle changes then you have a leak.

stock throttle body....thanks guys for the vacuum leak suggestion, i didnt get a chance to pop the hood yet with all this rain and shit today. at least its somewhere to start, thanks!

If it isn't a vacuum leak, then try re-loading your tune and doing the idle for 10 minutes, idle for 7 minutes with the A/C on full.

If it never happened before and the tune has been in for a while I would have to say vacuum leak as well. and do what he said about learning the idle.

 

[classix_stang289]

alrighty guys, quick fix. Just got a chance to pop the hood right now and indeed it was a vacuum leak. The tubing for my mechanical boost guage seperated from my brass tee fitting causing the leak. Quick repair and test drive and issue is fixed. Thanks to all, i appreciate it

Is that a normal thing that needs to be done after flashing a new tune?

Yes, it is.

 

[DarkTrak]

Yes, it is.

Hmm. Learn somethin new everyday.

Not really.

I was about to say, I've never had to do any special procedure for idle after reloading my tune....

Maybe something new with the 5.0?

I've always heard that you need to let the car relearn the idle with and without the A/C on for several minutes after loading a new tune.
