It seems everytime I get an underbody wash w/ the TA it'll misfire randomly until i hit high rpms, then it'll take off, it last for a week or two then go awway (ii'm guessign drying off) It happened once and went away, then I was at the do it yourself car wash with the high pressure hose, I sprayed the inside of the wheel wells, again...misfiring...I know i Have a low hanging 02 sensor wire that may be the culprit but i need to lift it up to be sure, anybody want to take a look at this? or suggestions?
 
I'd look more at the o2 sensor, as your car will go into open loop (ignoring the o2) at higher throttles.
 
Ok i will check that, but one time i unplugged my maf sensor, and my car starts and runs without it......weird?

I changed the wires last time this happened, Next thing is 02 senso, looks like the plastic zip tie that usually holds up the wire snapped. so it's just hanging low...

I'll get back with you guys

Thats normal, the car will run in speed density mode, using the map sensor instead of the maf.

I would fill the o2 sensor connector with dielectric grease to keep the moisture out, and see what happens from there.
