Hello everyone....i need some help because i planned on going to the track this wednesday and yesterday my car started running like crap. the check engine light has be coming on every once in a while for the past few weeks but only for like 5 minutes at a time.. finallly i went to start her up yesterday and spuddered and stalled out... a couple more cranks and some pumps on the gas and she started...seems to run ok in the higher rpms but still runs like **** and stalls out at idle always.. i guessing it is the O2 sesors as they control much of the air/fuel ratio...anyone know what could be the problem....the check engine light is constantly on now and it just bogs out and stalls...thanks in advance.
