2000 Camry running wierd

[Lars64]

..working on my sisters Camry w/V6...changed the plugs and VC gaskets..put everything back the right way and now the check engine light is on had it scanned and came back with nothing wrong...it has a high idle @ 1500-1800..if you turn it off it does not want to fire back up inless you let it sit for a few minutes but when it fires back up it has a high idle and it will not go down...I'm a Certified VW technician not a Toyota tech...did I miss something because it ran fine before hand...thanks for any help because this site has helped me alot so far and have no where else to turn

The MIL is on and there's no code stored? Who did your scanning? I've never heard of that situation.

Assuming you disconnected power while working on it, the ECU will need to relearn how to properly control the IAC. Mine took a while (several trips) after I did similar work on my 03 Avalon.

..my local Autozone did it..the light went off and about a mile it came back on..took it back and there is no codes..yes the battery was disconnected for 2 days...I have done a walk thru with the hoses and plugs..all of them are hooked up...I went and started it again and the idle went down to almost 300 I gave it some gas and it shot back up to 1800 and styaed there..I took it around the block and under load it hauls butt but died coming to a stop sign...got it running again and got it home and dis connected the battery again and now on here...she needs it back tomorrow and I can not give it back to her with my nieces in it...
