P0430 Infiniti -

Question

P0430 2000 Infiniti I30...pulling a P0430 in combination with P0505 (idle air) and P1320 (coils, etc). Have replaced all 6 coils previously and scanner is not indicating a coil malfunction but rather the generic P1320 code. Replaced the IAC along with complete throttle body assembly 6 months ago. Pulled the ECM looking for possible evidence of burned chips, etc. and visual inspection showed nothnig. Any assistance is appreciated.

Answer 1

Did you use factory coils and IAC valve? sometimes aftermarket parts will cause the problem to comeback. Unfortunately for the P0430 code the only solution is probably the catalytic converter. For the P0505 code you could try performing the Idle Air Volume Learning procedure. Instruction here: http://infinitihelp.com/diy/i/projects/infiniti_i30_idle_air_volume_learning.php
