rpm's won't drop until stopped
I have searched and didn't see anything quite like this. Should be simple for you guys. Rebuilt engine with mods listed below.Also new ignition coil,Borg Warner. Was doing this before the engine though. Idels just fine at start up. While driving though when coming to a stop the rpms stay at about 2k untill I come to stop then drops back down to about 900. Doesn't matter if cold or warmed up. It started doing this when I did the headers. I also at the same time descreened the MAF. Any suggestions? All other sensors are original with 140k except for oil pressrue and block temp sensor. I appreaciate any ideas.

I took the IAC out last night and cleaned it as well as the hole in the bottom of the TB.Drove to work this morniing and still doing it. I don't think vacum problem as car was doing this before new engine when all vacum was hooked up in original location and it hasn't worsened. Stock TB also and spring seems tight. My buddy works at goodyear and we hooked it up to the scanner and it came back driver side 02 sensor out. Would this cause it maybe?

Yes sir Josh I will fix that 02 ! Car had been running for 15 min and driven when we tested the 02. Thanks for the advised though.
Yes computer is tuned for all delete air and egr and mods. No reason to beleive computer is problem because every other Mod I requested is working perfectly. no skip shift, fans on at 185 and no other codes were thrown so I don't think is computer issue. Going to try Josh's suggestion and hopefully fixes. Thanks to all for help. Will post with results
