I just installed my vafc and my check engine turned on. The car also smells like gas, and its not running right. i bout this used, could it be that the old owners settings are still on?

Or could it be that the connects arnt all good. I was in a rush when i put everything together

I also didnt install the VTM, can anyone tell me what the VTM stands for ?

I really wanna drive the car and i dont get to drive it too much so ANY INPUT will be greatly appreciated

 

Double check the connections. My guess is that your MAP sensor wire isn't connected properly.
