Default Me, myself and ES300. Need help! CEL and tranny slipping after MAF and IACV cleaned

Hello everyone!
Glad to be a part of the community, albeit after an issue arose with my car :S
My CEL came on and tranny feels like slipping on 3rd after I cleaned out my MAF sensor (is mine a Karman Vortex??) and IACV (used recommended sprays). Mine is a '98 with 177K and in great shape. The tranny was replaced at 110k along with water pump and timing belt. My battery was very weak as well and I just put a new one in. The reason I cleaned out the MAF sensor and the throttle body and IACV is because my car was stalling after starting at very low rpm. I also pulled the ecu, efi and hazard fuse (kept them off for an hour) to reset the CEL and ecu, and it helps for a few mins sometimes but the same problem will start again and the CEL will come back on.
My idle rmp will usually be around 700-1100 and whenever I put the car in park or neutral, it goes up from 750 to 1000-1100. I have no idea what to do nex....any help would be much appreciated!

Thanks for the response. I really hope I missed something to connect the last time. I'll go back in again today and post back. Thanks a lot for taking the time to comment!

Did the whole thing over but no luck. Could my IACV be causing this?

Have you scanned the CEL for codes? It could give you a clue at what to look for. You said you cleaned your IACV, so you had to remove the vacuum/coolant hoses that go to the throttle body. Double check them and make sure you didn't mix them up.

I honestly don't see why anything you've done would have caused an issue, unless you messed something up. I did the same things to my 98 and it runs fine. There is a chance that you somehow damaged the MAF.

P1705 - Direct Speed Clutch Sensor Malfunction. It's a sensor on top of the transmission.
