well I'm not sure if I can be of any help with this issue...but my care is throwing a code of P1259 malfunction with the VTEC...NO SHIT! My car feels like an LS! My VTECH does not engage and feels the same all the way thru the power band like the other guy was saying.....does anyone know about this code? I am also using a VAFC but I had it professionally installed....it's been working great for about a year now no problems....GRRRRR...I hate this!
