NEED HELP PLEASE!!! Change plugs truck wont run right

Hey Guys I need some help please.
I am doing maintenance this morning and now I have problems..
I have followed each guide on TW for these items to make sure I did everything right.

I changed each spark plug one at time used dielectric grease and anti seize, cleaned MAF sensor with CRC MAF cleaner sprayed the wire things lightly and sprayed down inside the tube, unbolted throttle body but left tubing on and just cleaned the dirt and grime with CRC TB cleaner and lastly removed secondary filter.
I did each plug/coil one at time to minimize any errors. I remove MAF from air box. didn't touch any wires. Lefted everything TB.

I go to start the engine and it didn't crank over right away but I think thats just the TB cleaner. then noticed the idle higher then normal (above 1000rpm), took it for a spin to see if things just need to burn off and the auto trans gears are not shifting normal.
Things just don't feel normal...... WTF!!!!
Anybody have any input

 

Disregard.....I forfor to unplug battery. Works fine now.

 

This was going to be my only suggestion. Glad you found your solution.

 

Such fear in the first post and sigh of relief(nothing to see here) on the second post.... i know this feeling too well. glad it was simple

 

I would be curious to know why a spark plug change and/or all/some of the other items mentioned caused the idle speed to double?

 

Not sure but I know from experience that after cleaning the MAF sensor and putting it back in (and disconnecting the battery), the engine will idle weird for the first few to several minutes. Sometimes too low, other times too high but after driving around for a bit it always goes back to normal. Probably an ECU readjusting thing.

 

Yep! From the mas cleaning and not a plug change. Happens to all vehicles if you do that to them.
