Question What did I do wrong

I just installed my p&p throttle body and now the car idles at 1000rpm and it seems to stick when I rev it up.Also it starts to increase and decrease in idle. All input needed.
Thanks Mike

Sounds like the throttle cable is stuck/sticking. Check that, make sure it is all clear.

Sounds like a vacume leak or your IAC isn't working right.

Well I took it off and put it back on and also did these steps...
Key off.
Unplug TPS.
Turn key on for 5 seconds.
Key off.
Plug in TPS.
Turn key on. Closed throttle should be 0%.

It's going to idle like **** for about 10 minutes. You need to drive it in traffic, then turn on the AC and drive 10 more minutes; Your PCM has to do an idle relearn.

Who ported the TB? It could be that it wasn't done correctly and its not sealing completely. And as far as the TB sticking when you press the gas all of my P&P TB's had that feeling compared to stock just takes some getting used to

NO ik that's fine I mean when you said idk about the ac part. It's to relearn the idle...because it idles differently but driving it should fix the issue it just needs to relearn it. I have one from the same guy and mine runs great

Update...I drove it it seemed like it stopped until I got home now. I drove with a/c off for 10mins then on for 10mins and nothing. I drove the car for over an hour and now the rpms also stay at 1000rpms. So what now?
