I have a 92 civic dx 4door with a 99 d16y7 swapped in, a z6 head on it, and a turbonetics turbo. Noname BOV and wastegate. It has an idle problem. It runs perfect above idle, drive it every day. At idle, it'll sit steadily at 2k rpm. Sometimes it becomes erratic, and drops to 1k, then climbs back to 2k, then drops again over and over. It also won't rev up at idle, it'll stutter at 4k rpm and refuse to make boost without a load. Its a p28 ecu. My buddy thinks the ecu is programmed wrong, I think maybe one of the idle valves is wonky, an o2 sensor is dead, or the map sensor is messed up. One of the readers. Anyways, advice? Anyone point me in the right direction? Thanks!
