i have a 01 tt and it started about a month ago were she would take it to work and let it sit all day well she work and when she went to leave it would start and then die or ideal ruff for about a minute or so. then it started that at about sixty or higher it would start running a little ruff and delay. and another problem is that it just started bringing on the traction control light at random times. the check engine light is on it sayes bank 1 o2 cencor bullow threshhold. and map cencor high out put. i changed a fuel filter and it has not did the starting problem any more but it still has the delay and the traction control light. i think im changeing the 02 cencor tomorrow but i fell like that is not going to be the end. please any ideal. it is all intermiten so idon't want to pay the dealer a 100 buck for them to tell me it was running fine well they had it.
