Air mixture sensor,code 29 coming on,running rough, been told check micro fuel filter under cowling, could this be the trouble or is it air intake blockage.

Cheers.

there is NO air mixture sensor nor corrosponding code.

code 29 is intake pressure sensor out of range.

sensor is either unplugged,defective or a lean condition is causing an intake manifold backfire.

all easily visible on the laptop.

can be measured with a multimeter,just more difficult.
