My car has traction control coming on and off regularly which changes the shift pattern to a very uncomfortable level. any ideas would be appreciated

 

ABS sensor is my thought. should throw a code i think.

 

Have the codes read and then proceed. It should definitly have a code stored if the traction control is engaging regularly.

Have your codes pulled and post 'em up here, otherwise our guesses would be just that....guesses.

I keep having the same problem with the service traction warning coming on but by the time I get to the auto parts store, they cant find the code because the light is off. I have been told it might be related to the oxygen sensor or abs sensor. And ideas?

 

You will have to get the codes read by a scanner that will communicate with the abs and traction control. Most part stores just have a code reader the will just read code for emissions. At least that what I have seen in my local part stores.

 

You are correct. That's why they can't see the code.

I really need an answer to this as well. It happens everytime I idle for a long time say 2 minutes, then the traction control light comes on. If I clean the throttle body it seems to clear it for about a week, can you clean the fuel injectors? I noticed a lot of corrosion on the fuel rail also. Should I replace it? I am about at my wits end.
