Car is fully bolt PLM Header, short ram intake, ebay exhaust piping with apexi muffler, and 255 fuel pump. Car starts up fine for about 3 secondw then idles bounces from 300-500 and cuts off. It is on the stock tsx basemap. No CEL lights were on or then. Maybe a bad pcv valve?

Did you get this figured out?

The answer is blatantly obvious. You're running a Base TSX map and changed multiple sensors. Your info fed into your KPRO is not congruent with what it (the ECU) thinks should be coming in.

Even if all the new sensors are brand new and OEM, was the base map running the car in its previous state well? Like bad sensors car ran ok, got new ones and it started failing ?

If you post your KPro Kal and a few catalogs I'll take a look for you
