2 months after the header installation n tune..ses light came on..checked it...p01133(fuel air metering)...it turns off one day..then comes on the next....would any of these cause the problem
1.24'' o2 extensions instead of 12''
2.ntk o2's....

im not sure if the aftermarket o2s i got from summit are junk or if the extensions are too damn long...any help?

right now it smells like fumes at a stop light..if i do end up fixing this problem..would it still smell like fumes?? *no cats -long tubes

I suggest you get some new O2s, Bosch PN 13111. They are the vette rear O2s. A few bonuses that these O2s offer is they have a longer harness which will allow you to do away with the extensions, and they are suppose to be a bit hotter which will help in preventing the problems your seeing now.

FWIW I have been running these same sensors for QUITE some time now without any issues what-so-ever.

1133...i have the same code being thrown along with 1153. I have the bosch O2's and they still throw those codes. My tuner said it doesnt affect the performance or anything. Im going to have him disable these codes all together. o2's run fine. the computer just doesnt seem to like them.

i have a header leak...between the header itself and the head on the drivers side...(hedman headers)...seems as if the hedmen gasket went to ****...so..i bought some gm gaskets....lets see if this will take those damn codes away
