My 22re is running rough and it feels like there is a load on it at 2000rpm i read the codes on it and the codes say that tps and afm and oxygen sensor but i never had a o2 sensor. I am stumped and need some help. Thanks

 

never having an O2 doesn't mean you're not supposed to. All 22re's had at least one, some two.

Anyhow, what are the actual codes? What year?
