I replaced the o2 sensor in my chevy truck; the check engine light went off for a week, now it's back on and is sucking up the gas.
here is the real problem: when the check engine light is on it runs great !
when the light goes out it becomes sluggish but will still run.

i purchased and had the auto repair guy use the code reader from my truck so this is how I know it's the o2 sensor.

now the parking light won't go out-HELLP !

thanks

what can I look for to remendy this problem?
