Default Car is studdering and miss firing HELP!

my car has the ses light on due to my long tube install cus i delted the rear o2's and AIR system. and thats fine it ran fine.
2 nights ago i changed my plugs and it was driving fine as well, i raced it and everything with no problems.

well today it was raing pretty hard. so i drive my car to work and i leave for lunch and i notice my car at idle is heistating and violently shaking and i try to rev it and it will barely even rev. thought i sucked up some water cus i have the FRA mod done. so i go back to work and park it later that night when i leave it does the same thing then i hold the rpms at 2k and it stays then all of the sudden bam everything is fine. drives fine.

so i go to auto zone to get the codes pulled. and of course i have the rear o2's and air delete codes showing but. 9 errors pulled up including

p0113
p0140
p0152

a couple were for the o2s and air and he said there was like a misfire on number 6 cyl.


im going back in a minute to make sure all the plug are tight so that isnt the problem. and clean my MAF what should i use to clean it?

any hlep would be apprecaited.

thanks

its plugged in to the lid and everything. i took my lid out and there was like a lil i mean little plastic piece that came off that was attacked to the lil plastic thing that goes around the resitor or w/e is in the middle, it feel off and went down in it, but i doubt it has anything to do w/ it.

also the wires brk a while ago that were hooked to the IAT sensor and i soldered them back up im not sure if they are making a fine connection with the solder.
