| the stalling has gotten worse over the past week. cold/warm enigne same stalling/hesitation. (NO hunting or high idle) The IAVC/AAC, air regulator, spark plugs, injectors (nismo 555), wiring harness, CAS, basically everything from a rebuild are less than a year old. the rebuild was done almost a year ago and car ran fine. just recently the syptoms started showing themselves. I connected Nissan Data Scan from Blazt (can send files of idle if you want). What I have done: -I checked the common connectors for corrosion (all were good since new harnes and sensors were installed at rebuild). -Vacuum boost leak test. I hear air from driver side, can't pinpoint if it is the side of the engine (turbo solenoid or wastegate on turbo) or at back of engine (driver side). -IACV/AAC & air regulator WD-40 cleaning (did not take apart) units were new. just sprayed WD-40 into the tubes several times (it seems to have gottem better but still hesitates but didn't stall) ***had the Blazt connected to monitor and set idle/rpm***
-disconnected the yellow femal connector on the IACV to set idle/rpm (750 +/-50) with idle screw but the rpm did not change. I turned fully CW and CCW and no change in idle/rpm (confirmed). -reconnected IAVC yellow femal connector and adjusted idle screw and noticed some change in idle. -ran ecu codes: 55 No faluts codes ***other important things****
-using the blazt, i turned on/off each spark plug noticed idle/rpm drop on all plugs except #4. -battery good
-alternator good
-checked injectors about a month ago all read 12-14 ohms (good)
-fuel fileter less than a year old
-i have the dreaded bealt noise on cold start up
-2 days ago, while parking, felt like the power steering did not work. could be because the idle/rpms were low. Any ideas would be greatly appreciated! I'm in west palm beach, Fl. here is my email and number: 561-301-9829 darkml@hotmail.net Thanks
