hesitation and wierd idle
hesitation and wierd idle for a few days now ive noticed somethin with the car.....sometimes when i floor it it will act like it wants to go....but barely goes...kinda feels like it stubles a lil....then after maybe 2-3 seconds it clears up like nothing was wrong and shoots out of there
also if its just sittin there idlin....the idle goes down a lil...feels like its missing....car starts to shake some....then clears up....
some have suggested my o2s since i just got the lts.....
plugs and wires are good.....
maybe i need to reseal my block off plates?
any suggestions

More than likely O2s, especially if it only idles bad for a few seconds (or a minute or two) and goes right back to running ***** to the wall the next second. Especially if you did LTs recently. Block off plates would not cause the said condition.
O2s have a tendency to go when LTs are installed for some reason, it could be the dirt/crap/coating burning off the inside and coating the O2s. Or it could simply have been almost time and pulling em' out, and tossing them into the new LTs could have been the last straw.

You can try, I have seen people clean their fouled up O2s and actually get it to run correctly. Its definitely worth a try since O2s are real easy to do (especially with those LTs), but I wouldent totally count on it 
Theres really not much you can do to clean them other than wipe them off and hope you do something. Usually if they are fouled, they are fouled good. But sometimes can be saved if it isnt too bad.

Did your car not throw a SES light for those O2's? I'm experiencing the same symptoms on my stock car at warm idle.I'm thinking my O2's are being lazy or something,but I've been told that the SES light is supposed to come on when O2's go bad

Hmm, weird. Maybe it's specific to the year of the vehicle. Mine's a 97 and has an O2 sensor that complains from time to time. I'll change it eventually, but for now, I just take out the PCM BATT fuse.
