Took the old girl out of the garage after about 6 years. Charged battery, checked tires and fluids and started her up. Was running rough and dash diagnostic said H44. Checked for vacuum leaks then took off pre cat driver O2 sensor it was Black! Changed it and now she runs well with no SES light on. Good to be back.
H44 Code 1994 C4 fixed 🙂 O2 sensor
