Air pump issue?
Всем привет
I used to drive without air pump for two years. Now i want to put it back to make rx work fine at idle.
So i installed all air pump staff, but left output to catalyst (on uim) blocked, because i lost my pipe.
So i started my car and it idles very roughly, after several minutes of idleing i can't touch anything under the hood. O2 sensor shows me 0.83 v.
When i disconnect air pump it idles fine, 02 sensor shows ~0.5v and temp under the hood is ok.
So what is the problem? Blocked output to cat or broken air pump?
Help me please.

at idle the air pump air is injected to what mazda calls "port air" which is ahead of the o2 sensor, so it will read lean.
its also probably going to raise the exhaust temp.
the engine should run better though
