I have been at this one for a while. Did the "tests" and everything seems okay. 444mv/719mv infin ohms on sensor. I hope it is not the ECU
I did pull the sensors and the Bank 2 pre and post cat had a little soot on them. Swiched them over to bank one today. Shortly after start up I got stored codes p1115 and p1119 I'm sure the rest will follow (not check engine light yet)
Sensors when monitored do seem to react.
For other reasons and maintenance, I have replaced the:
Coil Packs
Spark plugs
Spark plug tubes and seals
Air filter
Cleaned the MAF with MAF Cleaner....wouldn't that affect both sides?
AOS lower tube (thought it could be AOS but only bank 2 seems to be rich or have black soot on the sensors) Thought that would affect both banks.
Things seem to be very sealed up. Removed oil cap.... got reaction....opened intake hose....got reaction.
I am thinking that maybe the sensors are incorrect...would that cause the codes to come up and run rich in Bank two? The sensors are spliced in and seem to have diff numbers on them .....017...357 etc..
Could the AOS be failing and only dumping into one side?
Thanks any help would be great!
