Ok I've sprayed the car at least 20x with no issues with this. When we fill the bottle we freeze it in a cooler and. Then fill it from the mother tank. Out of nowhere today the car started breaking up on the shot. Im wondering if my buddy left the bottle open in the cooler and it drew water into it? Im gonna catalog it tomorrow also because I may have fouled an 02 sensor and it may be dumping fuel into one bank of cylinders. Could these be my problems?anyone experience similar problems?

 

Ran 112 leaded through it. Killed my 02 sensors causing it too run way too rich.

 

Depending on what system you have it could be the nozzle is twisted 180 deg out and not directly spraying into the throttle body.
