i will keep updating for someone whos having same problem.
i changed TPS(throttle position sensor) today, but no change.
while i was working i found a crack on my exit pipe right before
cat converter. it was leaking my smoke. i was wondering if it has
any affect on my O2 sensor located after cat converter.
thinkin smoke leaks out of that crack and O2 sensor thinks theres
not much of O2 coming out my engine and trys to put more air into it.

not sure if thats the cause but i will seal it off weld it. and replace
both front and back O2 sensor tommorow.

they were both $51 each from autozone, bosch brand.

also changin my IAC valve cuz my mechaninc doesnt want to trust
the one got from dealer real cheap.
