What!!!!!
My car has trual duals..rear 02s have been deleted..the front two have homemade extensions on them for the longtubes.
I went to have my car dynoed and The driver side 02 was not reading so it was running rich. I had a spare 02 laying around so I put it in now it's saying the driver side is running lean...could this be just another bad 02 or could it be because I have a 90mm intake and tb on the car and it's not getting enough fuel..but that should be cause both sides right?
So should I just go by another 02 and buy some extensions and put on there.
And I also heard you could get a 02 for a certain year model corvette that already came extended?
