Running bad, O2 sensors?
my car has been running great all until about a week ago...
i started the car one day and it began to idle hard and run poorly when pressing on the throttle, it would kind of clear up on WOT but right back to running rough as soon as i let off the pedal. when the car gets to operating temperature it clears up alot of it but i can still feel the problem.
A few different people have said it is more likely an O2 sensor gone bad so ill try that first, but how do i know which one it is? i realize i should replace them all but that will need to wait a month or so. the computer isnt throwing any codes...
