Unfortunately it's not widely available in NC yet. On the other hand I have 2 stations within 20mins from me

thats awesome. i want us to get e85 here or somewhere near here. i found a thread on how to take care of the egr valve. i need to find out how much an egr block off plate costs. id rather just block it off that way i dont have to worry about the code reappearing. does anyone know if you can find a o2 fix at the parts stores.

For the o2 fix, go to the parts store and look for the anti-spark plug foulers. Take one of them and drill it almost all the way through and leave the other one like it is. Plug the o2 sensor into the one you drilled into, then screw that one into the other fouler. After that you just screw it into your exhaust and your problem should be solved. $4 fix

All you need to do for the EGR issue is to zip tie the line on there. I haven't had mine blow off since I've done that.
