93 Octane

readapted throttle, still wont idle. car seems to drive and pull fine though. possible ignition relay issue. swapped with starter relay for now.

-8 to -10 LTFT at idle and tons of black soot on rear bumper. This has always been this way but -10 LTFT seems excessive.

replaced throttle body and performed relearn. let car idle 10 minute recommended time and car shuts off. restarted and car shut right off as idle came down.

All but throttle pos look good. Cyl 4 pulling 3 degrees.
