Ive been having some issues with my apex since the other nite on a poker run...all of a sudden I am getting code 13 and 14 flashing after riding the sled once its warmed up. If I go out and start it up cold, no codes....But once warm, codes are flashing and it wont idle, I mean WONT idle. Its still running good just no idle....gotta really plan out what your doing....thinking there is a broken wire somewhere...anybody have any ideas where these wires are at on this thing?????Theres actually snow here so I gotta get it goin as soon as possible...thanks guys

Intake air pressure sensor (open or short circuit) (pipe system)
 
there's water or moisture in the hose and sensor. Check sensor voltage. Between the pink/white and black/blue wire. With engine not running with switch on, postive probe on pink and neg. on other, sensor pluged in. it should be between 4.75 to 5.25 volts dc. any differ reading take it inside and let dry and then do the test again. Still the same low voltage replace
 
I had the exact same problem with my Apex MCX 290. Reading code 13 and 14.

My problem was , that the vacuum hose going to the backvalve (that is suplied with the MCX kit, because the sensor cant stand turbo pressure)
was broken.

Then the air pressure sensor didn't read any vacuum when starting
