new guy with idle question

[High Plains Drifter]

Hey guys, great site. I've been checking it for the past couple of days and finally decided to jump in. Also, I need some advice from all you SHO gurus out there.
Our stock '93 SHO has been doing weird things on idle lately. I cleaned the IAC valve and assembly. I also cleaned out the throttle body. The MAF was clean. I did all this three days ago and the idle straightened up and seemed fine. Last night I did an oil change. I also put in a new air filter. Standard WIX paper element. Now the thing has a warm idle of 1200 rpm as opposed to 900. What's up with that? Do I need to drain the CPQ and let it reset just for a new air filter? Should I just take it out on the road and blow the cobs out of it and see what happens? We're getting ready to drive about 1000 miles this weekend and I don't want any surprises if I can help it.
Thanks for any help and/or tips. I appreciate it.

You might want to disconnect the battery to let the computer reset itself and see what it does. These shos are very moody (especially 93's) so starting there would be a good try. Especially since you did alot of cleaning to your sensors, etc. The computer may need to reset to all the new information that it is getting better now. Good luck.

I figured a re-learn session might be in order. "Moody" is an understatement! Thanks.

Welcome to the board.

Remember that after the battery has been reconnected and the engine started, you have 70 seconds to add all of the loads that the engine will see at idle: (ATX?) Shifter to D, A/C, headlights, turn steering wheel side to side.
