Slight Exhaust screw up

Tell me if I'm being too paranoid...

I have an EFI system on my motor (Holley Commander 950). I had a custom stainless exhaust installed and forgot to mention the need for an O2 sensor bung drilled into and welded into one of the exhaust pipes. I can't do stainless welding.

How much trouble will I cause, if any, by driving it back to the exhaust shop to correct this problem?? Will the lack of the O2 sensor cause any problems with the EFI system? Only planning to drive it 20 miles back to the shop.

I would go back and have it added. Without it the computer has no way of knowing the fuel mixture so it can`t add it`s info to help the computer.

I am guessing but you must have driven it home so take it back. If there are going to be any codes because of the lack of the o2 sensor they are already set so drive it back.

Good Luck

All thats going to happen is your mileage will suck until you get the O2 bung put in. Its the same as when they fail on a new car.
