Ok yall can i get some help to get these pesky things figured out . so im getting codes...
172 -(HEGO2 sensor voltage indicates "lean")
411 -(Cannot control RPM during Engine run self test--Low RPM check)
First the O2 sensor....does this indication mean i need to fix some things to make it run more rich.....or does this mean i need a new O2 sensor?
I have no clue what the 411 code is all about.
The car seems to be running fine but i hate seeing that check engine light on.
All help is much appreciated.
