Pulled Codes..

[Black87GT]

Ok well i went out an bought a code reader, and pulled the codes this morning, this is what i came up with (got the codes 2 times tho??)
i got:
with a KOEO (Key On Engine Off) test
code 34: EGR Valve Position(EVP) sensor or pressure feedback EGR (PFE) sensor: signal voltage out of self-test specification limits, or signal voltage above closed limit during normal engine run operation or, signal indicates insufficient EGR flow.
and with a KOEO (Key On Engine On) test
code 42: Exhaust Gas Oxygen (EGO) sensor: voltage signal always "rich"(high value) - does not switch
then i also got two code 11: System pass with the Key On Engine Off test

So what do i need to do? no idea really what any of this means???

ok just erased the computer, and now im only getting code 11 with the key on engine off test, so i guess it was reading the old problem with the EGR, so all is good now...
now i should just replace the oxygen sensors??

if you get eh o2 sensor code again, i would.

[Black87GT]

yes i am still getting the o2 sensor code, im in the process of removing them, little bitches are tight as hell.. lol

[phillysrt4]

they are a pain in the ass thats for sure
and they're the kind of thing where you want to take your time and put anti-seize on your replacement
