whats up guys.. well im tryin to get the car ready to get tuned. its gsr boosted. the codes used to throw 01 and 43. i know 01 is o2 sensor. and 43 has something to do with fuel. for now the car is running stock p28, fmu, i took out the inline and installed a walbro. i ran the codes today, there was no o2 code, however 43 came up again.

once its at the shop ready to be tuned with Neptune, the injectors will be installed. is it ok to drive the car from work and back and little here and there until i get her tuned next week? still waiting on few more things.. also i just got my fpr and gauge inthe mail on sat. il be installing that today.

 

If you're running way to rich, that can cause code 43 as well.

 

how bout running too lean

 

Either one can cause a that code to pop up.

 

If the is a lean/rich code be very carefull especially with boost
