i bought my evo about a month ago and it ran great and still does but sometimes when i come to a stop the car will want to die but doesnt and then idles fine. My car is running modified Autronic PnP ecu. Modified meaning that the board was sent to Autronic to be modified so it outputs 4 ignition channels unlike the stock Evo ecu which only has 2 channels, its also has the Autronic 500R CDI ignition box. I am running a Tial BOV and i have tried to adj the BISS and it doesnt seem to change the idle either way i turn it. Also i saw that one day the TPS was unplugged on accident and was wondering if that TPS being unplugged for who knows how long messed something up with the TPS or even the IACV
