ive got the MCC light on and when using the flash codes ,it gave me 43...
i am using a PBV (FPR) in my car since 1 year w/o problems,but maybe it is this one..

ahm...car went well even when light is on ,no stuttering nothing just sometimes the enginge stucks in idle mode....because of very low RPM

I've got that code also, since my motor went into the car.

I am going to try the fuel filter first, then the O2 sensor.

WTF did you just say?!

If you think that tha MAP sensor may be throwin a code 43, you're wrong.

I was originally throwin the MAP and fuel system codes. I replaced the MAP sensor and that one went away, but 43 has stayed.
