Walker Pro 5/7/2013Hello,
Unfortunately, I am not sure what might be your problem, but I have some suggestions. However, if you have coolant leaks into the combustion chamber it may cause rapid poisoning of the O2 sensors. Have you been using good quality sensors? The correct Walker sensor numbers for your vehicle are as follows:
The upstream sensors for both the front and rear will be Walker 250-25001
The downstream sensor for the front is Walker 250-24346
The downstream sensor for the rear is Walker 250-24391
If you have any further questions or concerns please contact us and we will be happy to help.
