ECU Trouble- P30
 

Hi bros...
I need some help... My P30 ecu ... CEL 14. idling up and down.
Did may things related to IAC but fail to solve it.
Finally changed the ecu, code disappear and idling became smooth.
Anyone can help tell me which part in the ecu will cause this problem?

hey i just did a jdm b16 swap and mine is throwing cel 14 too....but its not iding bad but it does rev up and down at 1500rpm, before the and after its fine. what ecu did you switch too? any other cel's?....

Still the same type...P30.
Mine i guess is ecu faulty. Before this it was fine...
Ur case, clean up the IAC unit first and see if becomes ok...

i used to have the same problem with the jdm p30 ecu..the idel was up and down and i have jdm b16 swap..so i switched to a chipped p28 usdm ecu tuned by a pro and the car runs perfectly well..i have heard so many negitive comments on jdm p30 ecu..
