car running weird
Check engine light came on, so i went and had it checked out, and the guy said the rear o2 sensors are bad and need replacement. Will bad o2 sensors cause this type of problem? It could be the spark plugs, but they were changed 6 months ago. It happens oftenb while when i get on it, and almost always around 3k and up..it also pulls uneven and nothcy.
Also ive noticed there is some play in the accelerator pad, could it be that? Sometimes it feels if i get on the gas quick it stumbles slowly up the rpm range with barely any acceleration, and sometimes it feels like if i push it slowly down all the way, nothing bad happens and it pulls.
Would appreciate any help, as this is driving me nuts.
