Need help! Oxygen sensors not working! Hi Guys,
I have been having this problem for the past few weeks...
I've been busting my *** to find the cause but not be able to succeed.
The car is constantly throwing P 0134 02 and P 0154 02 codes saying that no circuit activity...I am using diablo sport by the way.
I have changed the oxygen sensors twice. No change... I have checked the fuses. No change... I have checked the cables. No change...
The fuel consumption is almost the same with my 455 pontiac engine. And the car is down on power slightly... There's quite a lot of gas smell from the exhaust however, my afr seems to be around at idle is 14,1.1 / 15,3.1
16,5.1 / 18,0.1 at cruise speed. And 15,3.1 at wot.
These readings tell me that the car is running really poor, right?
But i can smell the gas on the other hand.
I'm completely confused.
Any help will be greatly appreciated.
