Howdy,

I'm flashing a code 34 (which I believe is a MAF sensor) and a 64 which I cannot find anywhere (OEM or other sources). Thanks. I replaced the EGR, O2, and MAF and still I'm getting slight hesitation and rich fuel. Spark plugs look OK and I'm put a fuel treatment in the tank. Still at square 1.
