SLK230 Check Engine light after Upsolute
CEL came on after chip was removed and reinstalled with original flash by Upsolute tech. Also ran terribly (no power) during this phase.
Chip removed again to re-flash with UPsolute code and CEL came back on again.
Error code: P0170- Fuel Trim Malfunction, 02 Sensor or MAF sensor.
Replaced 02 sensor and CEL came back on after several hours of driving.
What has happened to my car?
