Rough/Rich Idle 10.0 AFR NA-T
Hey guys looking for some input here. It's an SC300 with an NA-T setup specs below
1992 SC300
60-1 Turbo
440cc injectors from 7mgte with stock resistor pack
SAFC2
12v Fuel pump mod
Rebuilt ECU Capacitors (Tanin)
Not going to list every part but I feel like that should be enough. Maybe a month ago the car was running was running fine off of albs boost. Ran great actually. Then all of a sudden Started to develop a stall whenever the A/C was not in the "ON" position. Read around the forums and thought cleaning the IACV valve would help this out, when ahead and did that. Got the car all put back together, started it and the car wouldn't hold idle.
Idle starts at 14.7 far, but as soon as it sits for a while it gets richer and richer finally to the point where it's at 10.0 Mind you the car sat for about a month due to my busy schedule with work. Game me the symptoms of bad capacitors, so I figured no big deal and sent out the ecu to Tanin for capacitor replacement. Received it back yesterday, put it back in the car, and same damn issue!
Running out of ideas so I'm just looking for input as if I'm looking in the wrong places. No signs of boost or vacuum leaks either. Let me know what you guys think!
