RE: OBD-1 Trouble Code. Please Help!
ORIGINAL: Bigdogbowl
Changed out my MAF sensor. Fixed the codes 172,176,181,189 and 556. Reset computer and no more codes but still a spark knock/ping. Did a KOER test and came up with:
311 Air system inoperative during KOER (Bank number 1 with dual heated oxygen sensors)
314 Air system inoperative during KOER (Bank number 2 with dual heated oxygen sensors)
It obviously sounds like my O2 sensors are bad but i have changed them about 5 months ago. They are the ones in my pipes right infron/under my firewall.
Are there anymore that i am not aware of?

Question? So if the air pump is not working properly to pump hot exhaut gasses back into the intake. That could explain why my car gets to running temp that I get a spark knock/detonatoin/ping when under load?
