Well last time i shut it off i restarted it and no check engine light... decided to take her out again and hammer it a few times and sure as shi* happened again, now checkengine and traction light stayed on...of course i loaned out computer thingy...im guessing and hoping speed sensors...i did just do all 4 rotors and pads and had to do some serious hammering to get rotors off. Maybe knocked something loose

This nails it on the head...
Doing pads and rotors is actually ridiculously easy on the ISF. People think since they are Brembo(or Lexus, since it says Lexus) believe they are complicated pieces to deal with and should be left to 'professionals'. That is BS, the calipers are the easiest type to work on and were practically designed for ease of swapping pads. Men have been working on their own car brakes since the beginning of the automobile, I believe we should all continue this trend. All that is involved for the pads is removing two pins, a spring clip, and a 13mm bolt. For the rotors; two 17mm bolts hold the entire caliper in place, remove those and set the caliper down on a jackstand or hanger, and your now at the rotors...if the rotors are stuck, there are screw holes on the rotor, use two bolts[size M8x1.25] to pop the rotors off. You can get those bolts at most auto stores or Home Depot.

If better fuel doesn't fix this, I would check for oil leakage down the sparkplug tubes. The seal between the valve cover and the head sometimes leaks a little and it could cause something like this. I once had a bad misfire problem that was simply a dirt track down the side of the sparkplug conducting when it shouldn't have.
