Lately its been getting harder and harder to start my truck, and today finaly it wouldnt start at all. After over an hour of cranking on it with jumper cables hooked up to it i pulled the plugs to see if they were fouled. Sure enough they were almost dripping wet. This is my 4th set of plugs in less than 10k miles. They seem to last about 2k miles or so. I know its still got really low timing and running pig rich for the N2O, but damn.

I went ahead and changed the plugs and it fired right up, but idled really rough. I put the logger on it and took it for a ride and my A/F gauge never fluctuated off red. It stayed in open loop, in the red. So after 3 miles i looked at the logs and B1S1 was reading a steady .2 and B2S1 was a steady .980. The misfire code said only one of the O2's were working and the A/F was being set by just one of them. Out of curiosity i looked into the trouble code logs from the past 2 months and they said the same. Only one is working. I just thought it was a normal missfire code from the cam and never looked into it before. I guess i should have. LOL

So now its time to change the O2's. I'll do it in the morning and post back up it it runs better again.


How much are they anyway?

 

Front 02's. You should be able to get them from the dealer for $78 each. That's the wholesale price. That's what I get them for.

 

called around all the auto parts stores and the lowest i found for Bosch was $71. One Tire Warehouse place has them for only $62, but the wont be in for a couple days.

 

You do not want a Bosch, get Delco replacements. And dont let the Autoparts guy tell you that the Bosch and Delco are the same just because they have the same number.

 

How do the Denso compare to the stock ones?

 

are the stock sensors Delco?

 

Stock ones are ACDelco, and are $89 each after a 10% NAPA discount and 5% military discount. And i had to go to 2 different dealers to get both because each dealer only keeps one in stock. BS!!!!!!!!!!!!!!!

But $190 later its up and running again. Maybe i should take it easy on the race fuel.

 

i went with the leaded proof bosch for 52 dollars a piece so i can run race gas if i want.

 

Really, do you have a P/N for those? I wonder if they will work ok.

 

When I got new ones, I shopped around and got ACDelco's online for $52 a piece.
