Last night come to a stop sign took off in first and it sounded like nam backfire so embarrassing then i shifted into 2nd and it came out of it came to the next to stop signs and did the same thing my set up is intake, header, and exhaust and a fuel rail my car is throwing a code 43 and im thinking it might me by O2 but if anyone else might know or has had the same problem let me know thanks

 

It could be that you are running very rich for a reason or another.

Reset your ecu first. If same code comes back. Test your 02 sensor. If it is bad, then replace and see.

anyone else have any ideas

 

why did you change your fuel rail?
