clovis,

I cant seem to steady out my idle. Ive tested the ISC and it passed with 40 on all coils and verified proper movement. TPS is at .65v at Idle, got it to .63 but throttle position went to 1, so I ran TPS ADJ and that put throttle position at 0 and TPS at .65. Adjusted Biss screw until I got as close to 30 as possible, the idle fluctuates so I cant get it exact.
Base fuel pressure sits at 43.5.
Idle is set to 900RPM, I tried 750 but its even worse.
1). Any boost, vac, or exhaust leaks?
No
2). Verified mechanical timing?
Yes
3). Verified base timing?
Yes
4). Ignition system
COP or Stock Coil: COP
Wire brand and Age: Custom 2 Months
Spark Plug brand, type and Gap: NGK-BPR6ES/.028
5). Motor health (Compression Test)
Not Done
6). Performed basic throttle body adjustments?
Idle Switch: Yes
Throttle Cable: Yes
TPS: Yes (.65V) 27-33 ICS Position
BISS: Yes
7). Compression ratio
8.5:1
8). Any known bad sensors or brittle wiring?
No
(OHM Racing Fusebox/Engine Harness)
9). Any DTC/CEL codes?
Emission related/Rear o2 (off with ECMLink)
10). Electrical system
Car off (not running): 12.4 volts
Car running: 13.9 volts
11). Base fuel pressure and injector values
Base Fuel Pressure: 43.5
Injector Size (cc/min): 1650 Fic HIGH Z
12). Properly calibrated and configured wideband sensor
Sensor Brand: Innovate MTXL
Calibration Date: April 2018
13). Type of fuel
Type: 91 Octane
Percent of Ethanol: 10%
14). Watched ECMlink how-to videos?
Yes
