I have an 04 rx8 I had to put new radiator hoses on my car the other day and went to start it the next morning and the traction control stayed on i had no power.I shut it off and pulled the engine fuse for it and put it right back in c.t. went off when i started it.drove it 1/4 mile to gas station and it came back on.I have the obd2 code reader but was hoping someone else excperienced this and it was something stupid any help would be appreciated.I dont want to spend hundreds on sensors if i dont have to.

I Took the air cleaner off the k&n filter needs cleaning.The plug from the thread Darkbrew suggested was extremly helpfulty ty for that.It was a combination while changing the radiator hoses the plug some how came loose and the throttle body had a good amount of sledge build up so i cleaned it and got a good connection on that plug she runs and idles great now the traction control light comes on and off when its supposed to and it idles down to 1000 rpm after i get on her no skipping or hesitiation.Thank you all very much for helping me solve this problem hopefully but not that hopefully i can return the favor in time ty again.This is truley what this sight is about.
